Working on the railroad.
Busy day in the yard today.
Wow, I did not know they used lines like that to charge train air on other cars.
Interesting.

Thanks for looking and commenting. I think my husband was saying it is used for the brake system.

Yes, it charges the train air, and therefore the car air reservoirs. They can't move cars without the train air being charged. The way Westinghouse Air Brakes work, the car brakes are set when train air is removed unless they shut the air valve off when uncoupled to keep the train air charged.
Not sure how they would move the cars without motive power though. Maybe they are just filling the car air reservoirs so the air in the car brakes don't deplete?

I know one way to move cars is to bump them. One thing to remember when a bumped car is moving it is absolutely SILENT. That is how accidents happen.
FRA has a rule for how long cars can be off "AIR" before they need another air test of the brakes. In order to get around that rule as well as to save lots of time, they will have the cut of cars put on air. In this picture what most likely happened is, the train pulled into the first track, when they cleared the other tracks on the far end they stopped and cut off the cars that did not fit into this end and double over into another close by track. When they were next to where the engine could reach the cars they had detached first they stopped and they hooked up that long air hose from the engine to those cars. When that train goes to leave they will double those cars back and will not have to make a major air test, just a simple set and release to make sure the rear car sets ( by the gauge on the ETD ) and releases.

Thank you for taking the time to give us all that information.
Thank you for the 2 thumbs up!
