Also, in Vancouver they already have a system that prevents deaths by jumping in front of the trains. On the Canada Line there are laser intrusion detectors that automatically stop the train if movement is detected on the tracks. On the Expo and Millennium Lines there are pressure plates that do the exact same thing. Translink found a solution to this problem that fit in with their situation of having multiple rolling stock on their transit system.
Honestly, I think this solution is much more feasible for most transit systems. Installing doors at a platform at every station is very expensive, complicated and is bound to fail sometime.
In Britain you will only find (full height) screen doors on newly built lines. They only exist in London, on the below ground stations of the Jubilee Underground line extension, completed at the end of 1999, and on the below ground core stations of the new Elizabeth line, opened May 2022. It is a main line/metro hybrid and now runs through to main lines both east and west of London, including Heathrow airport. It is similar to the RER lines in Paris, which started in the 1970s. Toronto has the UP (Union station-Pearson International Airport) Express train line. It has full height platform screen doors at each terminus, but not at the intermediate stations.
Tbh the UP express only having doors at the big stations makes sense bc YYZ and Union both board the UP express from outside meanwhile Bloor and Weston both have outdoor platforms for the UP express so platform doors is kinda useless
the Automated peoplemover in North American airports has screen doors. they should consider doing that for New York Subway and the BART in the bay area.
the simplest problem for New York is the one that was glossed over from the report: not all trains are the same size. At present, we have 8 car trains of 60 foot cars, 10 car trains of 60 foot cars, 5 car trains of 60 foot cars, 4 car trains of 60 foot cars, 8 car trains of 75 foot cars and 4 car trains of 75 foot cars. and that's just the B division. Any PSD system would need to know what kind of train is pulling into the station and respond correctly every time without fail .
They have platform screen doors at Bart Oakland airport air train terminal. It would be very nice for them to install them in more Bart stations and platforms
As a regular SkyTrain rider in Vancouver, I can say that their current track intrusion system is less than ideal. First off, there are two designs of that in the system: the pressure plates at all Expo Line stations between Waterfront and King George, and the laser based system on all Millennium and Canada Line stations (plus Sapperton and Braid on the Expo Line). As such, they cannot be used at all when there is heavy snowfall, in which case the system will be turned off and staff will monitor every train, necessitating them to run slower and less frequent. Because the track intrusion system is activated whenever there are obstacles on the track, emergency brakes will be applied to the train at full force, regardless whether a human or a water bottle is on the track. This is the most frequent cause of injuries while on the train. The easiest line to install platform screen doors is the Canada Line, as all trains are identical with the same door layout. However, they were omitted because of mismanagement that plagued TransLink throughout much of the 2000's when the line was being built. In the Millennium Line, PSD's can also be installed as only the Mark II runs there, however because it shares the same track system as the Expo Line, that means Mark I's can also run there as well. Mark I's are the short stubby cars that have two doors per side, as opposed to three per side on the Mark II and III. While PSD's with wider doors can accommodate both Mark II and III's (despite the different spacing between cars 2 and 3 on both sets), it is the presence of the Mark I's that preclude such PSD installations. BC Transit (who operated the system until splitting into TransLink in 1999) never anticipated the Expo Line to have ridership grow so rapidly, and as such, the Mark I's were designed as no more than a small people mover vehicle, leading to severe overcrowding on those trains and totally unfit and ill-suited to ridership levels of today (Mark II and III trains handle overcrowding much better). With the management troubles at TransLink, they opted not to replace the Mark I's around 2010 (which was the projected end of life for those trains) which made the situation much worse as the Mark I's are so poorly built they vibrate much more than newer trains, leading to a worse riding experience, alongside the lack of air conditioning unlike every other trains. Mark II and III's were properly designed to be high capacity rapid transit vehicles from the start. Fortunately, this problem will be rectified with the delivery of Mark V trains (5 car sets instead of 4 cars) from late 2023, and the whole order of 41 trains will be delivered until 2026, finally replacing the suboptimal Mark I trains, something that all riders very much look forward to. These new Mark V trains still have the same door layout as Mark II/III and as a result PSD's will work with these new trains.
My local station had something similar installed recently. The differences: They are manual, someone has to open the gates when there's a train. The gates also close the entire platform, not just the edge.
6:04 Ha! Stood at that station, exact same spot on my commute home each evening. As that platform gets quite crowded, that’s one station that could use these doors and likely falls into that 27%. That said, there’s no political will power to spend money on infrastructure of any type in the states, where deferred maintenance is the rule.
The clip you pointed out was actually stock footage I got from Storyblocks . As for political will, I do agree with that point but I also think that there really is a need for a fundamental rethink on how infrastructure projects are executed in North America. Way too many times projects go over-budget and/or behind schedule.
Maybe we can do a standard rolling stock on the SkyTrain! Or maybe we can start with the Canada Line and then if we standardize the rolling stock for the other lines we can add platform screen doors later
For the narrow section of platform at 5:28, if passengers were allowed to walk from 1 train car to the next, maybe that section could be cordoned off to allow alighting only, with boarding allowed only from other stretches of the platform that are wider
because when North American transit agencies are saying they put safety first, they actually don't. They care more about money and make laughable excuses to not installing PSDs.
I feel like New York could use the smaller ones instead of full height. Same for most other cities. They just need to actually do it. Don’t worry about the cost, just do it.
Well NYC employs a diverse rolling stock each with different lengths between doors, so it wouldn’t work there unless NYC homogenizes it’s rolling stock
@@thomasgrabkowski8283 japan introduced a new type of platform screen door that can adjust based on the type of train with varying door positions and sizes. Its in Osaka and opened recently.
If your trains have conductors (who stick their head out of the train's side to check that it leaves a station safely) then you have to use half-height ones as full-height ones will block the conductor (which is probably why Japan uses the half-height design at many underground stations too)
A big problem with platform screen doors is if a train comes in and has to stop short for some emergency. The train doors won't line up with the platform doors trapping people.
You can setback the doors slightly so people can walk between to the open platform doors and escape the vehicle. It does restrict capacity some but there are also exits in front and back of a train. If its a more modern walk through train, smash the windows. Both windows on the train and station can be broken with the emergency hammers.
Meanwhile in Singapore, even before platform screen doors were installed, a train that stopped short ended up only being able to open the driver cab door to let passengers on board evacuate, probably as other doors had a safety interlock that could only be released when the whole train was in the station
Whoa! What is up with all the BART hate in the transit tuber community? BART is actually pretty good system with a ton of capacity and pretty much constant expansion and improvement. BART is still planning to install platform-screen doors on most of its stations. This project was paused because of the new trains switching to three doors instead of two. This upgrade was judged to be a lot more transformational than platform screen doors and was this prioritized. Also, despite the weird obsession that some transit tubers have over platform screen doors, there are a toooooon of other upgrades that are both cheaper, faster to build, and a lot more transformational. Our transit services need to first learn how to run before they try to fly. There is a lot of work that needs to be done before platform screen doors are the main remaining priority. Platform screen doors won't do much for services that barely muster enough ridership for 30 minute frequencies (*cough* MARTA *cough*).
In Thailand the MRT has full height platform doors. The BTS has the half height doors on about half of their stations. I'm not sure why some have them and some don't,,,,,,,,,,,,
Philly use two types of rolling stock but it is on different lines. So they don't have compatibility problem. Except for underground stations which have pillars none of the elevated segements have any obstructions. And since its already open air, half height would be enough and weigh less. There is nothing stopping it short of just money and political will. Heck the underground stations are so dilapidated they might as well rip it up amd redesign it from scratch and include screen doors
Singapore also has pillars like in 5:31 but all the way flush along the platform edge, & can still use platform screen doors as the pillars are positioned exactly in-between the train doors, though this prevents the doors from having additional emergency exits in-between them in case a train at the station needs evacuating and it hasn't lined-up yet with the platform screen doors. The pillars also get in the way if we want to change the trains' door layout e.g. from 4 a side to 5 a side per car e.g. with the line passing thru Changi Airport station planned to be connected to & taken over by Thomson-E Coast Line (TEL) by 2040, whose trains have 5 doors per side per car, while the East West Line that currently serves this station uses rolling stock with 4 doors per side per car instead (as TEL is newer & later on we decided to add more doors per car so that considerate passengers who stand in-between consecutive doors instead of beside them, to let more passengers on board, don't have to walk so far to the doors when alighting)
Political may be the truth and you have to put up with some passengers that would say they don't want them, claiming they have a freedom to behave any way they want to. I know I may be the mean man for blocking people and I might sound like if I am a man that comes from the big fortune 500 corporation world but there is nothing wrong with telling the truth. I also don't believe in fortune tellers, etc.
This. The reason why platform doors are common in Asia is precisely because a ton of those metros were very recently built. Retrofitting these new appendages on the platforms is usually pretty tricky. The vast majority of older metros anywhere in the world don't have them. Most of the metros in the US are pretty old, hence no platform screen doors. This is not rocket science.
I think the bigger question is…. Why do a very limited few rail systems have Platform Screen Doors when the vast majority of the world manages perfectly well without them.
Exactly. I think it has to do with "How many people are being transferred on each Ride per Trainstation" (accidents) aaaand "How happyand healthy are the people that get transferred from each station" (suicide). Seems in North America are not enough deaths to equal the cost 😬
@@residentCJIt is only expensive in the US and Canada because of poor planning, mismanagement, and inexperience. Far poorer countries could afford it. US prices are just bloated. Also people can accidentally slip and fall not just suicide. And if you think this is uncommon, you just don't ride enough US transit. People getting into tracks(trespassing not suicide or falling) is common in the US which can be prevented by platform doors! In fact trespassing is more common in US than other parts of the world. Heck US mental health is among the worst among developed nations which only justifies platform doors even more. It also prevents people throwing trash on to the tracks which can cause problems leading to delay amd higher maintenance. Third, they decrease dwell time as riders know where to wait instead of chasing doors. Doors also reduce the noise experienced by riders. NYC passengers are subjected to jet engine level noise. This is horribly unacceptable. Lastly, they allow stations to have climate control which most NA stations do not have. Even if the station already have AC, the energy cost would be significantly reduced. This by extension prevent rain and snow from drifting into elevated or surface stations. Once again reducing slip and fall, and cleaning. If anything it is a no brainer to have them. Most stations in the world don't have them because the first design came in around the 80s and only popularized in the 90s and 2000s. It is relatively new. The US is just backwards.
@@neurofiedyamato8763 The retrofitting cost mentioned at 6:00 does indeed sound expensive. If those 3 stations in NYC subway each had 2 platforms of 4 doors x 10 cars each, that works out to an average of ~US$400,000 per door. Meanwhile Singapore did the same to 36 stations from 2009-2012 for ~S$150m (~US$110m; when the cost had finally fallen low enough for the gov't to fund it); with a total of 78 platforms of 4 doors x 6 cars each, that's an average of ~US$58,760 per door (from Westinghouse) (maybe because labo(u)r is cheaper here)
PSD is a security feature and must be installed in all Metro stations In India we Manufacture platform screen Doors indigenously and it's very Reasonable
America has dozens of them, unless you meant something that you didn't make clear. Here's a short list, more or less from east to west and north to south: Boston MA: Heavy rail subway, light rail, commuter/regional rail, BRT subway, buses, and ferries. New York City NY: Heavy rail, multiple regional rail systems, aerial tram, buses, and ferries. Philadelphia PA: Heavy rail, regional rail, light rail. and streetcars. Baltimore MD: Heavy rail subway, light rail, water taxis, buses, and regional rail. Washington DC: Heavy rail, regional rail, light rail (under construction), and buses. Hampton Roads region VA: Light rail and buses. Charlotte NC: Light rail and buses. Atlanta GA: Heavy rail, streetcars, and buses. Miami FL: Elevated heavy rail, elevated large-scale automated people mover, BRT/busway, and buses. Cleveland OH: Heavy rail and buses. Dayton OH: Trolleybuses and buses. New Orleans LA: Streetcars, buses, and ferries. Little Rock AR: Streetcar and buses. Memphis TN: Streetcar and buses. Chicago IL: Heavy rail, regional rail, and buses. Detroit MI: Streetcar, automated people mover, and buses. Milwaukee WI: Streetcar and buses. Minneapolis/St Paul MN: Light rail, regional rail, and buses. St Louis MO: Light rail and buses. Kansas City MO: Streetcar and buses. Oklahoma City OK: Streetcar and buses. Dallas/Fort Worth TX: Light rail (largest in North America), regional rail (3 different systems), streetcars, busways, and buses. Houston TX: Light rail, busways, and buses. Austin TX: Regional rail and buses. El Paso TX: Streetcar and buses. Albuquerque NM: Regional rail, BRT, and buses. Phoenix AZ: Light rail and buses. Tucson AZ: Streetcar and buses. Denver CO: Light rail, regional rail, and buses. Salt Lake City UT: Light rail, regional rail, and buses. Seattle WA: Light rail, regional rail, buses, and ferries. Tacoma WA: Light rail and buses. Portland OR: Light rail, regional rail, aerial tram, and buses. Sacramento CA: Light rail and buses. Los Angeles CA: Heavy rail, light rail, regional rail, BRT, and buses. San Diego CA: Light rail, regional rail, and buses. All of the above cities also have intercity rail service provided by Amtrak, for what that's worth. It's worth the most on the northeast corridor.
This is a bit of a myth. Most major US cities have metros/subways. There are a few large metros that have recently grown and still don't have metros. But all the historically large cities have some type of rapid rail system. NY, Chicago, SF, Washington DC, LA, Boston, Seattle, Portland all have pretty good rapid rail systems. Even Miami and Atlanta have metros of some description.
As a railfan I dislike platform screen doors because they obstruct the view of the trains. I saw them get installed on Taipei Metro over a 4-5 year period. They initially put them at the busiest stations and eventually all stations got them (half height). Newer stations underground received full height doors.
I actually kind of disagree, that are safer, yes they are safer on one level, when it comes to assault, suicide, and just accidentally falling. But another level, what if you had an event like the uk, just had rare yes, but I can see the train basically being a coffin. I think partial is actually better, over all. Even though I like the look at the glass, and seems it's nice for noise reduction. Someone also mentioned detectors in subways. So I think if you combined both a detector, and a partial it should find. You may even a full glass to create a waiting room/lobby as pre curser, but good create a nicer feel, *tho expensive.
When metro train passing through the station, it generates noice and dust, having screen door is not only for safety but also for the passenger comfort and station cleanses. I love the metro in Asian cities, they are clean, quite and safe.
You buried the lede... It's $ that under-funded systems don't want to spend the dough on to save a single life. Simple as that. The technical reasons besides ADA requirements are flimsy at best.
Nationalize the metro systems and mandate them for all stations. The problem is these so called “private” rail companies don’t want to regulate themselves. That’s why other countries don’t have this problem these things are mandated by the government.
Most things that are called “public” are already government subsidized anyway, it’s just favoritism to allow those utilities and transportation companies to suck tax payer dollars and profit off them.
I guess in the US its really that the car (automobile) wins and public transportation is just a jobs # for politicians. In Boston, everyone knows the MBTA is a disaster (that has been having baby disasters) but the people who would do something about it just drive (and now WFH) . If you want an excuse to not do something ask MBTA
The riders of American metro rails can get pretty out of hands. They would probably break the glass because it is not their and they would deface them with graffiti which would leads to higher maintenance cost. They figured why bother. Human beings are replacement but making a few more bucks for themselves is way more important.
Also, in Vancouver they already have a system that prevents deaths by jumping in front of the trains. On the Canada Line there are laser intrusion detectors that automatically stop the train if movement is detected on the tracks. On the Expo and Millennium Lines there are pressure plates that do the exact same thing.

3rd rail?
Honestly, I think this solution is much more feasible for most transit systems. Installing doors at a platform at every station is very expensive, complicated and is bound to fail sometime.

If those 3 stations in NYC subway each had 2 platforms of 4 doors x 10 cars each, that works out to an average of ~US$400,000 per door. Meanwhile Singapore did the same to 36 stations from 2009-2012 for ~S$150m (~US$110m; when the cost had finally fallen low enough for the gov't to fund it); with a total of 78 platforms of 4 doors x 6 cars each, that's an average of ~US$58,760 per door (from Westinghouse) (maybe because labo(u)r is cheaper here)
PSD is a security feature and must be installed in all Metro stations
In India we Manufacture platform screen Doors indigenously and it's very Reasonable
Well money talks. As for safety, that’s only for lip service.
The problem is that the money was spent for lobbying and not on the rest of the economy
Well it's simple really. If people can't get injured and blame someone else, how can they sue anyone?? It's the whole basis of American society.
Bigger question.. Why America don't have metro systems
America has dozens of them, unless you meant something that you didn't make clear. Here's a short list, more or less from east to west and north to south:
Boston MA: Heavy rail subway, light rail, commuter/regional rail, BRT subway, buses, and ferries.
New York City NY: Heavy rail, multiple regional rail systems, aerial tram, buses, and ferries.
Philadelphia PA: Heavy rail, regional rail, light rail. and streetcars.
Baltimore MD: Heavy rail subway, light rail, water taxis, buses, and regional rail.
Washington DC: Heavy rail, regional rail, light rail (under construction), and buses.
Hampton Roads region VA: Light rail and buses.
Charlotte NC: Light rail and buses.
Atlanta GA: Heavy rail, streetcars, and buses.
Miami FL: Elevated heavy rail, elevated large-scale automated people mover, BRT/busway, and buses.
Cleveland OH: Heavy rail and buses.
Dayton OH: Trolleybuses and buses.
New Orleans LA: Streetcars, buses, and ferries.
Little Rock AR: Streetcar and buses.
Memphis TN: Streetcar and buses.
Chicago IL: Heavy rail, regional rail, and buses.
Detroit MI: Streetcar, automated people mover, and buses.
Milwaukee WI: Streetcar and buses.
Minneapolis/St Paul MN: Light rail, regional rail, and buses.
St Louis MO: Light rail and buses.
Kansas City MO: Streetcar and buses.
Oklahoma City OK: Streetcar and buses.
Dallas/Fort Worth TX: Light rail (largest in North America), regional rail (3 different systems), streetcars, busways, and buses.
Houston TX: Light rail, busways, and buses.
Austin TX: Regional rail and buses.
El Paso TX: Streetcar and buses.
Albuquerque NM: Regional rail, BRT, and buses.
Phoenix AZ: Light rail and buses.
Tucson AZ: Streetcar and buses.
Denver CO: Light rail, regional rail, and buses.
Salt Lake City UT: Light rail, regional rail, and buses.
Seattle WA: Light rail, regional rail, buses, and ferries.
Tacoma WA: Light rail and buses.
Portland OR: Light rail, regional rail, aerial tram, and buses.
Sacramento CA: Light rail and buses.
Los Angeles CA: Heavy rail, light rail, regional rail, BRT, and buses.
San Diego CA: Light rail, regional rail, and buses.
All of the above cities also have intercity rail service provided by Amtrak, for what that's worth. It's worth the most on the northeast corridor.
This is a bit of a myth. Most major US cities have metros/subways. There are a few large metros that have recently grown and still don't have metros. But all the historically large cities have some type of rapid rail system. NY, Chicago, SF, Washington DC, LA, Boston, Seattle, Portland all have pretty good rapid rail systems. Even Miami and Atlanta have metros of some description.
Yeah - it makes no sense that we do not have these.

As a railfan I dislike platform screen doors because they obstruct the view of the trains. I saw them get installed on Taipei Metro over a 4-5 year period. They initially put them at the busiest stations and eventually all stations got them (half height). Newer stations underground received full height doors.
It's the funeral industries lobbying.
well psds in sg were first used to save air con anyway so
I actually kind of disagree, that are safer, yes they are safer on one level, when it comes to assault, suicide, and just accidentally falling.
But another level, what if you had an event like the uk, just had rare yes, but I can see the train basically being a coffin.
I think partial is actually better, over all. Even though I like the look at the glass, and seems it's nice for noise reduction.
Someone also mentioned detectors in subways. So I think if you combined both a detector, and a partial it should find. You may even a full glass to create a waiting room/lobby as pre curser, but good create a nicer feel, *tho expensive.
When metro train passing through the station, it generates noice and dust, having screen door is not only for safety but also for the passenger comfort and station cleanses. I love the metro in Asian cities, they are clean, quite and safe.
You buried the lede... It's $ that under-funded systems don't want to spend the dough on to save a single life. Simple as that. The technical reasons besides ADA requirements are flimsy at best.
Profits over people!
Nationalize the metro systems and mandate them for all stations. The problem is these so called “private” rail companies don’t want to regulate themselves. That’s why other countries don’t have this problem these things are mandated by the government.
Most things that are called “public” are already government subsidized anyway, it’s just favoritism to allow those utilities and transportation companies to suck tax payer dollars and profit off them.
I guess in the US its really that the car (automobile) wins and public transportation is just a jobs # for politicians. In Boston, everyone knows the MBTA is a disaster (that has been having baby disasters) but the people who would do something about it just drive (and now WFH) . If you want an excuse to not do something ask MBTA
You need to relax a bit more when you talk and not seem so tense.
Sorry I get quite nervous when speaking in front of a camera. Public speaking is just not my strong suit.
Yea all systems need platform screen doors!!!
We prefer useless light rail
Emotionless
You know I am in Singapore right? I am safe so sorry for your you are not safe
Same in China too

Money is the only reason. If they did build more, most likely it would reduce other maintenance expenses, and cleaning.
The riders of American metro rails can get pretty out of hands. They would probably break the glass because it is not their and they would deface them with graffiti which would leads to higher maintenance cost. They figured why bother. Human beings are replacement but making a few more bucks for themselves is way more important.
Because we’re a third world country
Them screen doors are not needed in China. Just a waste of money
Why not? Those doors help so much
They don't help if they want to jump off the platform
@@johnnyo7621 So thats exactly why they needed screen doors in order to prevent people from jumping off the platform
@@ninjapirate123 That is true but now days it's just totally not necessary at all to hold people back.
@@johnnyo7621 its for safety
