The best improvement one can make to low end motive power is to increase power pickup, thus sending pure, unobstructed juice to the already handicapped motors they come with. Fortunately, IHC made it easy to do...they simply were too chintzy to put an extra set of wipers and wire in. They did however, put in all the necessary details to add a set yourself...
Note the bracket holding the stock wiper...
...is present on the sides with no wipers...
...making it simply a matter of fabricating another pair, mounting them like the stock ones, and wiring them in...
...just make sure to clean the excess flux of the soldered joints...
...and that your wiring is properly oriented.
The results are fantastic, it crawls through plastic turnout frogs without stalling and has much better low speed control. Because it now has eight wheel pickup, it is also not as easily affected by dirty track.
