Mark I believe it is called thick and tacky red grease is excellent for gears on wheels sets especially on diesel's, but even steam engine any piece of grit or dirt or even a rug fiber can jam up the works, I had a mth diesel that drew excess  current around 4 amps that's exactly what the problem was I cleaned out the gears on the truck greased the gears and all was well only drew 1 amp or less depending if the smoke was turned on or not!
