Shaun,
Check if the Run/PRGM switch is in RUN. This switch locks TMCC engine to rum in one direction. I did not see a video of your engine running in reverse. If the engine is not running correctly see if there is a train club in your area that has TMCC or Legacy that can perform a engine reset for you. You can also post where you live (City State) as a forum member who is located near you may be able to help you out. Good luck
