I built one of these and can report that there's plenty of room for the motor and a flywheel in a 31. The main problem is that the central transfer box results in short driveshafts to the bogies which restricts their rotation. I got over this by arranging for the transfer box to slide laterally.
If I were to do another project like this, I'd use a central motor with long driveshafts to transfer boxes on the outer ends of each bogie to minimise driveshaft articulation.
