Yeah, I have to admit at times I get a little creeped out by the squealing, shuddering, rocking and overall questionable condition of some of the train cars. There was one in particular a while back that I was very happy to step off of - I forget if it was for a scheduled transfer, or if we actually got off to wait for the next train. Do you ever look around and see it in the other passengers eyes that we're all thinking the same thing - "Is this a moving coffin?"
