Smr Simple!

Thanks for the reply, but I got it figured out. I was trying to add the AC4400 loco and was have problems adding it to the maps excisting in the game. I could add it to any map that I installed afterwards, but not original maps. However it is working now and I have no idea what I did to make it work...

Is there a complete idiots guide to adding new locos in the game? I have searched everywhere and cant get anything to work
Thanks in advance
