How to fix a coupler that won't fire or stay coupled on MTHTrains Toy?
If the coupler on your MTHTrains Toy does not fire or stay coupled, it needs to be cleaned. Wipe it with denatured alcohol (not rubbing alcohol) and let it dry.
Why won't my MTHTrains Toy engine run when I first turn it on?
This is normal. To prevent accidental high-speed start-ups, Proto-Sound 2.0 is programmed to start up in neutral anytime track power has been turned off for several seconds.
What to do if MTHTrains Toy engine will not leave the initial neutral setting?
Check to be sure the battery is installed and fully charged.
