<{POST_SNAPBACK}>the 4-4-0 chassis basically exists unter the M7 and frankly its about time we had a nice 4-4-0
I wonder how similar the components would be? If you look at the service sheet for the M7, it shows that the motor is in the firebox area, between the rear driving wheels and the leading bogie wheels, whereas on the T9 and all other 4-4-0 tender locomotives it would need to be rotated horizontally through 180 degrees. So if the M7 chassis was used for a 4-4-0 tender locomotive, it would be sitting in the air gap beneath the boiler.
Unless, by "the basic chassis" you mean the components e.g. bogie pivotting arrangement and the experience of balancing the 4-4-0 / 0-4-4 wheel arrangement?
I agree that it would be very nice to see more ready to run 4-4-0 locomotives and (dare I say it!) 4-4-2's
