Operating GG-1 on O-60 Fastrack

James:

While I do not have any of the Lionel or MTH scale GG1s and I operate on Fast Track using 048 curves my experience with what is listed in the catalogs and on the box flaps of locomotives is usually incorrect as to minimum curve requirements. Many of the locomotives I own operate on 048 curves just fine even though they are listed as minimum curve 054 so operating your scale GG1 on 060 curves does not surprise me.

The manufactures are just playing it safe when they introduce a new model and even though a locomotive has been out for several years they still list them as to the same minimum curve even though we operators know better.

If you loosen up the pilot trucks on the JLC Gs and grease them at the pivot points they will easily negotiate 072 curves and switches.  At least mine do.  I can't speak for anything tighter than 072.

About three years ago, I purchased a Lionel GG-1 with Magnetraction and a Pullmor motor.   At the time I was running O-81 K-line tubular track.  At any speed above half throttle, it would fall off the track.  I sent it back.   A few months back, I bought another Lionel GG-1, same set-up, and it runs absolutely fine on O-45 tubular track.  My guess is the first one had some type of center-of-gravity, two inches above the pantographs.
