Until the bugs are worked out, save your money or buy something else. Currently playing the game; full throttle forward made the train crawl up to 9 MPH, currently it's rolling *backwards* at 10 mpm and just nestled to a complete stop. This is the passenger section of the game, played another section called Cajon Pass where the locomotive gets "stuck" at the same section. Rebooted. Restarted game, rebooted XBox, same results. And no issues with other games, just this one.
Doubt there's a refund for this so I'm hoppefully helping others not to suffer my same fate.
