Amtrak Questions

Hello everyone,

I had a couple of questions about Amtrak.

Are there two conductors aboard or is the crew member up front considered a fireman or assistant engineer?

On trains that run Superliner equipment, if a private car or heritage class car is added to the end can you get from the high-level cars onto the lower ones? And is the Amtrak crew allowed to enter a private car?

Be safe,

Gregory
