Yep, that’s your typical fouled Leslie S2M. Not only are the internals of that horn worn, but there was a whole lot of humidity that day.

Strasburg 90 has a Reading 6-Chime while my whistle is a 5-Chime. That thing uses a ridiculous amount of air haha.

Of course! The EMU cars seen in this video are Silverliner IVs manufactured by General Electric and Avco. The Silverliner IIs that SEPTA had were manufacured by the Budd company. The Silverliner IV cars have doors at each end of the car, but they actually lack center doors entirely. Those are filler panels where the center doors would've been located, meaning no emergency exit. The NJ Transit Arrow II and III cars have those center doors instead of the filler panel. The doors at each end can board passengers, but at smaller stations, the conductor only opens a few of the doors. At the center city stations, the engineer opens the door a the very front to speed up the boarding process. The emergency exits are marked by red and white tape surrounding the window on the exterior. The large bumps in the roof do house HVAC equipment, but they are mostly for dynamic braking, which the NJ Transit Arrow cars lack.

@@sepa2401 Hi, thank you for your reply, it is very useful to learn from. When I first picked-up on the name 'Silverliner', I had been researching Budd RDCs, they were a surprise since I had been unaware that Silverliners even existed. Good to confirm about the raised Roof sections being for HVAC and D/Bs. On the RDC footage I have seen, all they seemed to do is spew-out diesel exhaust Fumes. Thanks again.

@@gp3829 The humps on the Budd RDCs are for the exhaust system and cooling fans. There are two engines underneath the RDCs, and I think they were manufactured by Detroit Diesel.

The Milwaukee Road

Yasssss :3

They almost never run them up here. Last time they were ran for revenue trains were during the 2016 Silverliner V shortage. This happened to be a qualifying trip for a trainee engineer to learn push/pull operations. They always terminate at Lansdale.

I also should’ve mentioned this! I’ve had to do the same with my horn valve. What type of horn valve are you using?

@@sepa2401 GG train horn air valve floor mount and stand 4" tall

@@vidrioandsonstrucking2422 I don’t have that type of valve, but I’ll try my best to help. Your leak could be occurring from loose connections on your hose. A good way to check is with soapy water (Simply spray it on the valve and hose connections and check for spots that are bubbling). You should then clean cut the hose and ensure a secure connection between the hose and the brass fitting. If it’s the valve itself however, you would want to clean the inside of the valve as best as you can, and then ensure the nut on the valve handle it tight enough that it doesn’t leak air. Remember to always use teflon tape on all NPT pipe connections as well.

Unfortunately, nothing much really can be done to change behavior at grade crossings without changing the actual infrastructure. That's why SEPTA added PA speakers in the early 2000s to alert people of second trains approaching at the crossings.

Yeah, the crossings circuits are set to activate early. Probably a good thing as trains have the probably to overrun the station and into the crossing.

@@sepa2401 You DO realize that there ARE impatient drivers. 30 seconds is understandable, but over 3 minutes is unacceptable. Same with pedestrians.

@@Rlotpir1972 Freight trains take much longer to clear the crossing compared to passenger trains, and they run through here often at night. The approach circuit is necessary.

Thank you! I’m glad we had a blast yesterday!

My D-5 already has some issues. The backcap set screw threads have completely stripped out, meaning the set screw can’t be tightened. I’m trying to contact Bendix for a replacement backcap and diaphragm since they still make them for the Bendix PH-2 horn. Haven’t gotten much luck from Bendix yet though unfortunately.

@@sepa2401 maybe try reaching out to Mike Muha if that doesn’t work

@@coasternamegenerator5611 I’m probably gonna drill and tap for 3/8” threads, and then put a coil in the threads to reduce it back to 5/16”

@@coasternamegenerator5611 Good news, I bought a Bendix PH-2 that was missing the short bell so I could use replacement parts (Backcap, set screw, spring, and diaphragm). I’ll give you an update if the horn sounds any better. I also used a buffing compound to smooth out the inside of the powerchamber to give the diaphragm a clean surface to resonate properly.

@@sepa2401 hell yea.

Yeah, it was great seeing you again Daniel!

Yeah, it’s a single tone P2, hence the “A” designation. It’s basically a Caltrain P2 with a dead #3 bell.

Oopsies!

Yep! Caltrain's main horn of choice on their locomotive and cabcar fleet are Nathan AirChime P2s with bells 2 and 3. Some of Caltrain's horns have fouled #3 bells where the #2 bell is the only bell sounding, so it's basically the same sound as a fouled Caltrain P2 without the #3 bell. JPBX 921 is a prime example. If you want a more realistic sound, I can use a longer air line from the valve to the horn so the horn tails off more.

@@sepa2401 921 has a horrible fowled P2 lol, they fixed 920 but 921 needs to be fixed aswell but the rest of caltrains p2 sounds nice

@@sixfifty_sebb My guess is that the poor location of the horns causes them to get clogged with diesel soot on the F40s, causing them to foul.

@@sepa2401 yea I think it’s at the bottom of the locomotive since caltrains horns are at the bottom of their cab cars and locomotives

@@sixfifty_sebb I could be wrong as I'm on the complete other side of the country haha. Probably depends on the locomotive, but the P2 is small enough to mount underneath due to its slim size.

The Market-Frankford Line M4 cars have small 3 chime air whistles rather than air horns. I heard in a RUclips comment that the M4s use "Ohio Brass Air Whistles."

Hahaha yes! He isn’t pleased with the Leslie S2Ms on the SLV IVs. As someone who hears these horns everyday, they really aren’t bad unless they’re fouled. I personally find the SLV V brakes to be even worse.

I've had these horns for over a year and they've worked mostly fine without issue. While mine is mounted on a bicycle trailer (which is sheltered from the elements), yours was under a truck where it's exposed to the elements. Even if your horns were not dirty on the inside, they could've still had issues due to moisture inside your air lines. Another thing is the volume and PSI you ran them at. If you ran them with lines larger than the horn could handle, that could've blown out the diaphragms. If you ran them over the rated 150 PSI, those could've also blown out the diaphragms. I would say however that you horn could've been defective from the start due to poor manufacturing. If the seat where the diaphragm sits on has chips, It's no good. If the inside ring on the backcap has issues, it also would have trouble sounding.

May I ask what problem you experienced with the horn? Did one or two trumpets sound, or was there no sound besides air blowing through the lines?

Again,they were NOT mounted under the truck. They were mounted behind the cab halfway up. So no elements had an effect on them. I keep my truck clean! Show time if you know what that is.

Obviously you don't much about classy trucks. I have a Bendix factory built and installed air dryer system on this truck. I'm no rookie here. Been doing this for 43 years. Have had several types if horns on my trucks. There is no debris, no moisture,no dirt ,they are spot less inside and out. The stainless steel diaphragms are just not as pliable as the plastic junk they had inside. I've tried decreasing the air pressure, increasing it,etc. Mine are straight lined off a half inch air line thru a manual hand valve. Which is also United pacific approved.

@@sepa2401 again semi truck. 128 lbs MAXIMUM ON AIR PRESSURE. I'm thinking flexibility, and diaphragm thickness.

Thank you! There is more content to upload!

@@sepa2401 ok thanks I like it ‼️‼️

High quality SEPTA without an internet connection!

Your welcome!

Thank you! Push pulls don't run on the Lansdale-Doylestown Line due to the close distance between stations, and the Silverliner EMU cars are better at accelerating and braking than the ACS-64s and Comets. This was a training run with a crew that was learning how to operate push-pulls, and it just so happened to go down the line where I was recording.

Yeah SEPTA is usually pretty on top of removing graffiti art from their Regional Rail Rolling Stock. Interesting that I saw a unit without its vandalism removed.

I can help you! Feel free to reach out via my email. Make sure to send pictures and send a description of the problem as there are many points of failure.

Interesting! So it looks like it's mostly serving the Philadelphia area right now. I've seen videos of 8006 in different places though.

Yeah trains in the rain are sweet! Hey that rhymes!

Yeah I was very excited to see the Push Pull equipment!

Yeah, the Push Pulls don’t run on the Lansdale-Doylestown line mostly due to how close the stations are to each other. Therefore, the Silverliner EMU cars are selected for this line.

Thank you!
