I was in the process of adding crewmen to each of my locomotives that did not have them, which was going well until I came to my Rail King Alco FA's. It appears there is just not enough room to add the crewmen to the powered loco without the motor knocking into them. It worked fine in my PA's but those seem a bit roomier than the FA's.
So, if I added the crewmen to the very roomy dummy A unit and ran the pair in reverse would there be any issues in relation to the motor? I like having the crewmen, but I like having an operating locomotive better. So, if it's harmful to the engine I defintely don't want to do it.
Thanks in advance.
