I converted over to Fastrack including the accessory track for uncoupling and unloading. Unloading works well enough, tipping the car, at least when empty. But the milk cars don't work. I have 3 and all worked on the old style track. Here they are lethargic to the point of not hardly moving. At first I thought it may have been the mechanism, but when all 3 showed the same symptoms I decided to test them off the transformer where all three worked just fine, nice and crisp. It's like there's a dramatic voltage drop on the accessory track yet I don't understand why as there is no circuit board yet when I was hooked to the transformer and went with very low voltage I simulated the effect. All contacts on the controller are bright and shinny, it is a new piece. Anyone else run into this? Perhaps re-wiring it to run off transformer voltage (which I thought it was doing off the track now, or am I wrong). Thanks for any insight. John.
