I tried building a train using some Amtrak Superliner cars and some SD-70 Locomotives which came with the Trains 2006 software. They install fine, but the motors are not running (idling). When I try to run the locomotives (I am using the DCC control), the exhaust smoke comes out of the stacks and the engine noise is heard as long as I hold down on the "W" key to run the train forward or "X" for backward. The engine even moves while holding the keys down. When the keys are released the engine dies again. Other locomotives supplied with Trainz 2006 install and run fine. Ideas Anyone??? Harold
