Here is the thing guys, I need some help here
1, Why would one buy this rather than the old Thomas
2. If the Remote Thomas works much better with DC power one could insert a small rectifier with an 18V DC regulator and a smoothing capacitor, this would let the Thomas run quite happily at a constant 18V DC on a standard constant voltage 14V AC or higher layout. this circuit build would not be large but I am not sure how much room there is inside the engine, you would need a small heat sink.
