I originally started with the old Railworks version back in 2009. I subsequently crafted a Donner route from scratch, spending over 1100 hours. Then my system crashed and I lost the file. Took a vacation from Windows after that and have just recently come back. Lots has changed. Sorry, but the old game IMHO, was much more realistic and my version of the Donner route ran was way more realistic. I am impressed with several of the new routes, which I have actually riden on live in addition to the Donner run. My favorite is the Innsbruck to Garmisch route, which, if you view the YouTube Cabride is incredible. Been on it and the Kufstein route to Innsbruck numerous times.
