Another note, RPOs were locked. They were manned by USPS employees (required to be armed) and were locked. Passenger or train crew could not pass through them. although I would guess they would let train crew through if necessary.
Normally, a train crew had no reason to enter a working RPO compartment.
However, there was a very small door that a Trainman could crawl through on the rare occasions that it was required. I worked with a lot of passenger Conductors and Brakemen, and none of them had ever used the emergency door.
