It needs a proper driving car enginespec not a wagon spec or an enginespec from a locomotive that gives the vehicle actual driving power .
It shouldn't move on it's own when you take power .
 
Try using my DVT enginefile : Kuid:45317:102635 which is on the DLS
This will allow you to drive the loco correctly that is at the rear of the train plus you'll get a realistic shove from behind when you open the throttle .
 
It will also need engine sounds , hornsound plus the interior which is everything that a normal loco requires in trainz to correctly work .
