Hello!
I am repairing a friends Polar Express with a Series 2 motor (6208616100), which unavailable on Lionel's website, and everywhere else for that matter! The gear on the motor shaft is sheared off leaving behind a pile of metal shavings.
The Lionel website shows the LionChief Berkshire Jr Mabuchi motor (6208653100) as an alternative choice.
Are there any issues replacing the original motor with a motor designed for a LionChief engine? Will it be as powerful as the original conventional motor?
Thanks for any information!
