Need Advice on 0-6-0 Speed Control Problem

I would think that adding more electrical contact points would improve things - I have done that many times with lightweight floodlight cars, tenders, etc. and it always helped.

"Anything below 10 smph and it seems to lurch/stagger with each chuff." I assume there is a cam located on either the engine or tender that is used to provide switch actuation for the chuffing. If that's the case, it sounds like a touch of lightweight grease is in order. 

Question: have you cleaned the wheels yet? At least one of the wheels appears to have a layer of crud on it. That's always step 1 for me!

Well, for starters, it can’t be nearly new if it’s PS2. It’s nearly 20 years old. George is correct. You need to first clean & lube things before attempting to diagnose. Clean the wheels, the rollers, and lube everything. Pickup rollers, & wipers need lube too. Conductive oil best here. Could be other issues, but always start simple and work your way towards the more difficult diagnosis. Check & make sure tether is fully seated. Also, post up the item # for better understanding of the exact model you’re working on.

Thanks. I did clean everything as best I could the first time. I especially cleaned the wheels and wiper contact. And that did improve things for a while. I'm going to do some additional tests this weekend and will post the results.
