So my 13 year old son has a Lionel TMCC GG1 loco with Pullmore motors that is very difficult to control. It is the only engine out of the 6 or 7 that he owns that will drive like crazy on part of his track which is only an 8x5 set of two loops and the other part requires turning up the power to get it to run. I have had this engine almost fly off the curves near the power supply and then slow to an almost stop on the back side of the layout. I have considered putting in extra power taps in the back of the layout but we change the layout design each time we set up and none of his other engines do this.
Are there better motors that I can swap out? Where would I get them and what do they cost?
Any help is appreciated.
Thx Roger Elliott
