Try downloading some goodies at http://www.train-sim.com/. Get add-on routes, engines (with improved physics) and others. Also, go here: http://www.mapleleaftracks.com/EN-USA/free.html to get a re-modeled Dash 9 ten times better than the origional. Also try getting the improved Acela at train-sim.com. Default MSTS is crap. The add-ons make it a class A simulation.
