TimeDelor Posted August 17, 2015 Posted August 17, 2015 What about the 12 Volt train motor, to a modern one that Lego uses today? Power functions motor without all the battery boxes or sensors in other cars. Like a motor with a small battery and sensor already on the train motor itself. It would be like running a 12V train(Example 7730) without the battery in another car. It would be compact as 1 part, but still retaining the motor shape and size used for the last 35 years. And the middle wheels would be included too, and the driving rods as well to keep that retro realistic look. Quote
