Greatest score of my train collecting life!!!

[Super]

Well, hopefully these don't fall into the common problem with this design of motor gearing as I have tried to fix many without much success. I just had another go at a Benkei that wouldn't make it up hills and had to give up again as I spent a whole day trying to figure it out, replacing gears and such. These type typically run fine on flat surfaces but will stall on the inclines. They are also found to have most all the spur gears in them split which, in my uneducated guess, was due to them using plain white plastic for the gears and not some hybrid or neoprene plastic. I have even seen these spur gears split on new in the box trains.
