Green Lights

[Bill]

On Amtrak cars I noticed there are little green lights(on the outside) on each one pointing straight to the next car. My question is what are they there for?

Think they show the doors are closed.

Actually, they are brake indicator lights.

I still don't know what that means...the brakes have air and work? I was beginning to think I was the only one to see those lights. Thanks I don't know much about the operation of a train.

Actually, this was discussed on this forum a few months ago.

That is something I noticed recently as well when the SWC came through Amarillo. It made it a lot easier to spot it amongst all the freights going by.
