Hmmmm....I'm sort of new to this, all I have is track and 2 locomotives, a couple cars. I have not cleaned the wheels, but I've only had the loco for 3 weeks or so. It runs fine on its own, my EMD F9 usually won't just stop moving when the coaches are on the track. I can try to tighten the joiners, as I haven't done so in quite a while. Also, how would I attach feeder wires to the power pack? The set came with 12 tracks, now I'm using about 24. I'm using the Bachmann EZ track, just thought to mention that. Also, I've noticed that some of my nickel silver straight tracks are different. I have 4 with some wires beneath them, and 4 without. Could that also have an effect on it?

I'm using a Prairie 2-6-2, and I've noticed that it runs slower when I also have my lighted coaches on the track, and at low speeds the locomotive will stop moving and the coaches will use the power instead. Is there a way to fix this or to maybe add more power? I'm using the dc power pack from the challenger set.

I'm going to guess maybe a #6 though

Not quite. It has the numbers, but for different kinds of track (at least that's what it seems like to me)

Which turnout would go with a 22' radius curve?

Thanks! I'll check the trucks and axles.

Makes sense. Thanks! Also, I have an EMD F9 engine from the Challenger set and I'm wondering how many of the Union Pacific 12.5' smooth side cars it can pull on a flat grade. The engine runs noticeably slower with 2 of the cars and at very low speeds the train makes a clicking sound. It's not the couplers and it's not the engine. Is that normal?

I wish they would make one of the newer TGVs with 2 power units and not just one functional unit and a dummy, if they could make them go in the right direction

I recently got manual turnouts from the 12-piece expander set. Is there a way to convert these into remote turnouts? If there is, where would I get the mechanism?
