Hello..new to the forum but been reading OGR and it's predecessor for almost 30 years. A few years back I bought a "NEW" 2360 GG-1. I have wanted one since I was a kid. But I'm sorry I bought this one. Anyway..I bought this POS (piece of S#&*) 2 or 3 years ago. Out of the box it would not run. Sent to Lionel (here I go again....had a consolidation that spent over 6 months back and forth to Lionel) and hoped for the best. About 2 weeks later I received a new engine (I scribed a mark on the one I sent back to see if they would fix or replace). They replaced. Woo Hoo....same problem....she'sa no go. I put it up on the self and swore off Lionel (and at them). After a while I wanted to take a look at it. After dealing with trains for about 35 years, I was never once not able to fix an engine. Well this is my first. It basically has 2 problems. First, very poorly made worm gear on the armatures. Full of burrs. I've seen this before in an MPC GG-1. I spent hours of filing, grinding and polishing. But one armature I could not do enough. So the other night I though how about changing the armature. So I pulled out my service manual and found 2 motor GG-1's, the 2023 Alco and the 600 series GM switchers all used the same armature. Hey I just happen to have an Alco motor. Hoping the specs were not changed I swapped armatures. This helped with the binding. But here comes problem 2. It would seem that the electronics in this engine cuts back on the current delivered to the motors. Free wheeling on the bench I could stall the motor with my finger. WHAT ! I ain't never seen a Lionel engine that you could stall with a finger by lightly touching the wheel. But I said let me try it on the track. Minus the cab in conventional mode it actually ran pretty good with 4 K-Line Madisons. Not as good as it should but usable. I put the cab on and tried it again. It slowed down just from the weight of the cab. But still better than nothing. Now I put it into command mode. That was the kiss of death. I would not budge. 20 volts on the track and I had to push it to get it going but it would stall at the first curve. Now I'm thinking it was not so much the binding, but an electronics problem. There has to be some type of current limiter that is not working correctly. What a POS. It would be nice to have a schematic or a block diagram of the circuit (I've been a tech for many years) but I doubt Lionel even releases that info to the service stations. They probably use a flow chart type of troubleshooting. I'm using a KW transformer, and MTH DCS. I have 6 other TMCC engine both Lionel and K-Line. They all work fine. Any ideas would be great. If this has been talked about before I'm sorry. I'll search the forum. Thanks Viggie

Did you actually measure the voltage being applied to the motors to see how much voltage you are losing through the controller? That measurement would validate your conjecture that the problem is in the electronics.
