So I'm working on 'upgrading' a route I've already made and I have a locomotive repair shop and I'm looking for parts of locomotives that you would find laying around a repair shop, such as engines, trucks (bogeys), etc. I'd like to have some help so that I can make the repair shop more realistic. The route is set in the present day, so it can't have parts found on steam locomotives, and is set in the USA, which means buffers are not needed. So, any advice?
