Interesting mod to run train with battery pack

5V. That's a fixed speed of ~42% compared to the take off speed of 12V. Quite fast, especially with Tomytec or Bandai motors.

 

Btw. it's possible to add speed and direction control by connecting trough the battery terminals of a Tomytec 6V tram throttle. Essentially replacing the batteries with the power bank.

 

The most elegant solution is to get a buck/boost converter circuit, connect the 5V to the input, set 12V as the output and connect a standard 12V Tomix throttle to it.
