The TIR_500 engine will not work with Raildriver and Open Rails. Whenever I press the Raildriver run key, I get the "WSOD". At first I thought it was the Thousands Islands Railway, so I tried on another route, same problem. All other locomotives run fine, just the TIR_500. Works fine with keyboard controls. I thought maybe I could use RouteRiter to prep the engine for Raildriver, it has a function to do that, did not work. I've attached the OR log and the Eng file in case it could help. Any suggestions, anyone? Cheers, rhs (aka gerry)
