Glen,
about performance of traditional open frame motors and their eligibility for DCC, i recommend to replace them with suitable can motors.
Mark Schutzer has written and published several tutorials about. To which i agree to 100% as a result of my own expieriences. Some of this old open frames can pull about 1.3 Amps when just running outside the loco with no load applied. At least you have to sqeeze a G-Scale decoder into which is able to handle the load.
The cause is the magnetical weakness of the magnetic forces of the permanent magnets developing in the course of time. These motor draw then a lots of amperes, but have very poor performance output. As compensation they can get pretty hot when running longer than 2 minutes. Not the equivalent of the amps they guzzle.

He deals with brass, but with the MDC Locos it is just the same about the technical and electrical problems. The only difference is, that the MDC loco are not out of brass sheet, but of solid die cast.
My 2 cents
