Reason: There are a massive amount of duplicate tags and incorrectly used terms when it comes to train-related tags. This is my attempt to partially clean them up. Here are some explanations of specific points.
New steam_train, diesel_train, and electric_train tags are added so that multiple units are not incorrectly tagged as locomotives. Obviously this won't change existing posts incorrectly tagged as locomotives, which will have to be gone through manually - I'll do this and make the necessary multiple unit tags if this goes through.
railcar should no longer be used because it refers to powered single passenger carriages, not unpowered vehicles.
subway should be aliased to rapid_transit because the latter already has tags like subway_train aliased to it
urban_rail_transit should no longer be used because it is too vague a term and the implications currently make several posts that should not be tagged urban_rail_transit in any case tagged with it.
If you have any questions, please ask.
