Installed Ian's "locomotive" (TrakTruk.zip) but it has some operational problems...
With throttle at 0, gear 1, reverser in forward, when you release the brakes, it jumps to 9 kmph.
With throttle at 0, gear 1, reverser in reverse, when you release the brakes, it jumps like a jack rabbit. Before you can stop it, it has usually run off the end of a spur somewhere.

Ian suggested I post here to see if anyone has, or is willing to, tackle the operational parameters.

This is a really neat vehicle and keeps the management happy 'cause you don't have to "borrow" a Dash 9 or Geep to explore routes.

P.S. Would also be nice to have an eng file that's in MPH for USA routes.
