Must it be NCE? I was going to get a Digitrax decoder for my Polar Express but I saw Kato recommended TCS. I know Kato has a relationship with TCS with their Kobo shop but I checked it out anyway. Even though TCS is $10 more than Digitrax, it turns out TCS' version have top and bottom mounted LEDs at the front of the decoder. When you switch to reverse when running cab forward, the white headlights go off and the red tail lights come on. I think TCS has the only decoder that does this for this model.
