I am thinking of re building part of my lay out as some type of industry that uses two locos to move rolling stock around within it. Is it common for a factory etc. to buy a used loco and just blackout the road-name and paint theirs over the top? I now that I have seen grain elevators were they just bought the loco and left it as was. I want to make the locos on that site look like they are part of it.
