Amfleet25124 posted:PCJ, not to turn this into a M7 conversation per se, but just a point of clarification. For my 10-car consist, the 2 non-powered rear cars were not included and are totally out of the picture. I would use them only for static display and 4- and 6-car consists. The aim is to have the powered cabs at each end (one running in reverse) of the 10-car train and using the two 2-car add-ons in the middle of the train as cars 4 thru 7.
I don't think my plans involved excluding any or the set cars. While I don't have my set out to examine, a look at the power car and how it connects to its companion non-powered car will tell you what you need to do, since the proposed second-set will be identical.
