Miguelito posted:Thanks, GGG, for your advice. Tapes are clean in both engines. Checked for lubrication - all is well greased and oiled (removed some excess grease in one engine's trucks. I run DCS with a Lionel brick and have had several engines running at the same time. Have other lash-ups that function well too. Still I get the differences in speed with these engines when lash-up is uncoupled, smooth running of both engines independently, and stall with breaker after a few feet in lash-up mode. May have to resign myself to not using this configuration.
when the speed difference is too great, they fight each other. Of course if one has something wrong, that can make it worse. Traction tires caught in the trucks, debris in the gears, dried out or no grease, etc. Even a broken wire off a truck can lead to these issues when crossing switches and dead spots in the layout. One engine stumbles while the other drags or pushes it.
You should pin point which engine's speed is off using other MTH engines.
