TOMY or Trackmaster voltage upgrade mod (high speed)

[Ucwepn]

hi, cool.

Ive been debating to either get a new motor for some of my trains or convert the C battery and the one AA trains to 3V. Wondering if you had advice on doing one or the other (or both).

thanks

C battery engines are the easier ones to upgrade. With AA engines, you need a tender or extra car to hold the batteries.

good to know, might be easier to just swap out the motor in the AA and AAA trains.
