I recently downloaded and installed the NAM and RTMT Interim T-RAM stations. I read the instructions before I installed, and I don't think I did anything incorrectly. I don't have anything that is LHD. I had no problems with crashes before I installed the two mods.
An interesting note: the game runs fine while paused. I put an in-road/avenue tram with a few stations (even though my city is a bit too small to start using them yet). When I unpause, the game crashes in about 20 seconds. I don't have anything selected at all when it happens.
Specs:
Windows 7 Pro, Pentium dual-core (2.60 GHZ), 4 GB RAM, NVIDIA GeForce 9400 GT
