I'm new to DCC, having found a great deal on a Model Rectifier Prodigy Explorer last week. I have a small HO oval so this should be enough right now. I have two MTH locomotives, an NYC 4-6-4 Hudson and an NYC PA. When I ran these with my DC power supply it runs just fine, the headlights light up and sound comes on, just didn't have a way to control the sound and other features. When I ran them with my Prodigy it runs, however no headlights or sound come on. My BLI and Bachmann locos all work fine. Any ideas? Thanks.
