I'm trying to play catch up since it's been a long time away from Trainz, so I apologize if I'm asking stuff that has been covered. Are there any general rules as to what will work and not work in T12 as far as older content goes.? Is it hit and miss or are there some definite "don't bothers" ? If there is a thread on this, I 'd appreciate being pointed in that direction. I'm looking through some of my old favorites and would like to have as many back as possible.Thanks.
