Hi all.
A few years ago, the motor died on my IHC 2-6-0 Mogul. I found a new one on ebay and succesfully replaced it. Here is a post that gives some background: http://www.modelrailroadforums.com/...move-shell-from-IHC-Mogul&p=260593#post260593
As I noted in that post, the locomotive with the new motor runs MUCH faster than the old. In fact, I've found during very infrequent use over the last couple of years that it actually is running TOO fast. I run a small DC oval with my MRC Tech II controller. I increase the power up to about 20 (which is about how high I have to turn it before most of my locos will start moving), and the locomotive jumps from 0 to "pretty fast" instantly. If I go any higher than 50, the loco actually runs so fast it will fly off the rails. Essentially there is now a very small power band where the locomotive is usable. Prior to the old motor burning out, this is not how the locomotive ran. it was always one of my smoothest runners, and would actually run slowly very well.
It seems to me that the replacement motor was not actually identical to the original. It seems as though it's wound to run at a higher RPM at the same voltage level.
I'm looking for simple and cost effective ways to slow the locomotive down for use around the tree this year. I could try and find a worm gear with higher pitch, but I don't know how easy it will be to find one that fits the same shaft and is the correct diameter to mesh correctly with the rest of the gears.
Or, is it possible to add a resistor or something in series with the motor to reduce the voltage delivered to the motor?
The other option I've thought of would be to invest in a DCC system, convert the locomotive, and then adjust the speed range in the controller (which I assume is a possibility). I'd go this route if I had a ton of time on my hands and $300 for a DCC system and a decoder. But I don't really have either of those.
Lastly, I could try to just order another motor off of ebay and hope the one I have now is faulty. This one is quite a bit of a gamble and I think would most likely be a waste of money.
Any thoughts or suggestions would be much appreciated!
