If you go to MTH’s website and click on service, and then click on documents, and then enter the product number for that P-47, all the instructions on “how to” will pop up in the owners manual......
one word of caution, some brands of tracks don’t play well with the 2 rail to 3 rail jump....I’ve had a couple of the 2 rail versions (-2) and I have very gentle O81 curves, and still didn’t like the way they behaved on Atlas track.....your results may vary,...the models I have are NYC Hudsons, and both of them got high rail chassis with blind center drivers....
