Here's a question of which I'm sure there probably is no real easy answer to although, maybe there is... Which direction do RR's require the locomotives to pull into a maintenance facility? Does it matter whether they back in or drive in cab first? Is there any such rule in the first place? This question leads up to another question I have. On my switching layout I have the engine facility at the far east end of the layout. The lead is at the west end of the yard. Most of the switching will be done using the lead (obviously) by the engine pulling and pushing the cars through the yard from the west end. A second loco could work from the east end though moving two or three cars at at a time to help break up and sort out cars. To me it makes sense for the loco's cab to be as close to the "action" as possible in order to give the engineer the best line of sight possible. So the cab would be facing east which means the engine would leave the engine facility tracks by backing out. I'm using Geeps and I know they are supposed to be bi-directional. So could I have between the four of them one or two with the cabs facing the opposite direction? Or would this look odd, because one could always ask, "How did they get turned around?" I'm probably over thinking this, heck its what I do.
