On a prototype railroad mail list a request for pix of railroad trucks and vehicles was posted. Seems all roads had delivery and maintenance vehicles. Found some of the pix rather interesting and this made me think about railroad vehicles on layouts. Perhaps this is an overlooked part of model railroading. I cannot recall on my past layouts or any that I have visited in almost the past 50 years ever seeing a railroad vehicle.
Any thoughts on this or have I just missed what many have added to their layouts?
