Building an 11 x 14 U-shaped N-Scale layout. I'm using code 80 Atlas Snap track. All the track is down, and I'm using an MRC Prodigy Elite 10amp DCC system. I did not solder the track. I have stringers down, but when trying to run my Kato EMD SD70M with a TCS K1D4 decoder, I get stutter starts, stops, and no movement. I checked the voltage with a DCC voltmeter and have power to the rails. What can I do for more reliable train running?


Sounds like dirty track, dirty wheels or a contact issue inside the loco. Is it the only loco that does that? Also remember DCC is a pulsed voltage similar to AC. So a meter will tell there is something there but not whether it what the decoder needs. There are many knowledgeable folks on the model forum.
