⁴ᴷ⁶⁰ Last Days of the 91-Year Old Nassau Avenue Interlocking

The MTA is in the midst of implementing a comprehensive signal modernization project on the G line, which will replace the 85+ year old signal system with a modern CBTC signal system. The old signal system was original to the construction of the line, and while it continued to be very reliable, it has become increasingly difficult to maintain as spare parts become impossible to procure. This video shows trains crossing over the switches controlled by the 91-Year Old Nassau Avenue interlocking, which was placed in service in 1933. Enjoy this last look at a brilliant piece of early 20th Century signal engineering!

Heartbreaking to see this go. I love the Subway because it truly is a time capsule to another more beautiful world

[@Roboboy]

Honestly should be preserved in an interactive exhibit in a larger transit museum, but also riders and the city at large deserve a modern system not running on ancient systems that are impossible to continue to maintain.

[@fiercingdragon]

91 years old? Wow. It sure has came a long way.

[@anonymous3738]

If G trains were to be sent to Forest Hills, not all of them have to run there. Some can short-turn at 21st St using the center track. Also, Forest Hills doesn’t have to be the local terminus as the tracks continue and 179th St, the last stop has a larger storage capacity.

Every interlocking must have its last day

[@ThaMastTransit_MSDWolf8420]

Wow! That's incredible.

[@j.buchholz1187]

Nice video. I wish you could have had a chance to see the controlroom. Quite a bit of the german railway system is still controlles that way, especially on second and third class routes. Keep your very explanative videos up, for me as a remebrance to the city i was born in. I loved riding the subway... red rooster, front car, and mom had a foldable stool for me so i could look out the front window.

[@michaelscott7706]

Bedford Nostrand still has an active tower.

[@TSgotstolengoddamm]

wow they really dont build them like they used to... this is awesome to know that such ancient technology is so reliable that it survived a few decades.

[@supermarionathan1426]

A few decades is an understatement bro…

[@user-dj7wv5ok2x]

@@supermarionathan1426Even THEN, it’s still a testament to the maintenance skills of the in-house crews.

[@Roboboy]

Yeah, it's more a testament to the resourcefulness of the agency and signal maintenance staff. It hasn't lasted 9 decades unmaintained. It's literally being replaced because it's becoming prohibitively difficult to be maintained anymore.

[@Xe99]

these are the videos I enjoy. thank you.

[@scottyerkes1867]

Wow. This is incredible👍👍

[@roncaruso931]

Thank you for these videos. I've learned so much about technology in the NYC subway system. Did you work for the MTA?

[@DANNYN224]

Sad to see it go

[@brayanbarreramtaproductions]

Rip Also How Did A R68 Get Here This Is The Last Time We Will Ever See That

[@4440bestbus]

That's an old video that was taken during Phase I of the CBTC project

[@leecornwell5632]

Eventually the iRT lines is gonna get CBTCS real soon. I have a real spriital feeling that the 6 Pelham line is gonna be the first line to get CBTC I'm telling you. I have noticeing that the 6 Pelham line be doing signal maintenances between Pelham and Westchester square. Including Manhattan I'm telling you. The Pelham 6 line is definitely starting to be like the 7 Flushing line. When the R62AS used to be on the 7 Flushing line they were doing the same exact thing doing signal maintenances and track maintenances and electrical improvements. I definitely know that something is definitely about to be switched around between the 4/6 lines Equipments I'm telling you.

[@brayanbarreramtaproductions]

@@leecornwell5632 yes

[@user-dj7wv5ok2x]

Many units bought, many units sold; not many lasting nine decades old!

[@jasonderr3525]

They'll probably do the same with Bedford Nostrand tower as well.

[@joes2085]

So when you say the switches are activated by a "lever", do you me by a human in the tower pressing an electric switch, OR a human on the track throwing a switch manually?

[@DJHammersTrains]

It’s electro-mechanical. The physical lever controls the electrical actuation of the switch. The actual locking logic however is implemented fully mechanically, as the levers are physically interlocked with each other.

[@theplug-pv2fl]

what will happen to the nassau ave interlocking

[@Bacon-z9x]

Is so sad for it to be abandoned

[@AMPProf]

Thank god

[@barrybshrekson864]

Ight well now i gotta go look at this hopefully its not gone yet

[@TheCTANYC]

91

[@leecornwell5632]

Building what? What's going on at Nassau station?

[@AirbusA310Fan]

You Better Not Tell Me There Was A Train On The Thumbnail 💀

[@Michael_afton698]

Aww

[@Kennedyhudsonrepublic400]

Now it’s time to say bye bye

[@josephortiz1990]

So What Exactly Is Going On Here If I May Ask You The Question About That Dee Jay Hammers Thank You Very Much And You?!:-\

[@TailsMilesFoxx]

you need to fix your whole grammer.

[@1940limited]

No need for a single operator. Someone else's job lost.
