I am running o gauge locomotives and one of the three that I have does not run at a consistent speed as a matter of fact it may change speeds several times during one time around. My track is approximately 37feet around. I have added 3 extra lockons which has made no real significant difference. Is this a locomotive or track problem. It seems that the locomotive either recieves to much current then again not enough. Help if you can. THANKS

Glad you are getting into the hobby. Is this a post war or new era digital? If it is newer, are you running it in conventional mode? In any case, manufacturer and engine type? - and your power source? Alfred

I am running Postwar manufacturer Lionel steam engine. I have 3 controllers and all give me the same re result with the locomotive. The controllers are 1) type 3 90 watt Lionel 2) Atlas 3) Train master 115 volt 75 watt made by Lionel. Hop this helps. Thanks

My first thought would be that this is a track connection or corrosion issue or maybe just that the wheels/rollers are losing contact through a build-up of grime. If that isn’t the case then I’d look for a loose wire between them and the motor.

Get some denatured alcohol and clean the rollers and wheels of that locomotive

Get some denatured alcohol and clean the rollers and wheels of that locomotive I would pull the shell and clean the contacts on the E unit and pull the back off the motor and check the bushings. Clean the armature as well.

Clean the face of the commutator while you're in there. It should be a shiny copper color when you're done.

I agree with the others, a good cleaning would probably do wonders.

All of the above plus: Look for cold (dull looking) solder joints...while the brush plate is off clean the slots between the commutator segments...clean up the insides of the brush wells..make sure the brushes move freely and the springs arent broken or weak...check for shorts (open) between the armature coils and armature shaft...also between the segments themselves..hope this helps...good luck Rob

Be nice to know if any of the advice was taken! Did any of it solve the problem? I'm just saying.

lmadsen, I don't know if your problem is for only one of the locos. Is by chance the problem a 2020/ 671 post war Lionel S2 turbine? If so, I had a similar issue, until the internal cleaning was done as outlined by others above. How are things going? Alfred
