Without seeming like I'm trying to be smart ass, I didn't know that SP2 is broke/broken... It installed find on my system and has certainly sorted out some of the originals bugs in the initial TS2010. I assume NV3/Auran are still working on SP3 for TS2010. IMHO SP2 helped make TS2010 the best version of Trainz released to date. Hopefully SP3 will make it even better...
