Description
More Heisler-inspired madness! This little oddity uses a Heisleresque drive system to power its lead and trailing trucks, transforming it from a 4-4-4 to an all-wheel-drive 0-12-0. The drive shafts to the trucks are linked to a gear box on the main driving axle, with the shaft to the lead truck passing under the 3rd axle. Note that the cylinders are inclined to accommodate the short wheel-base of the lead truck.
This was meant to be a turn-of-the-century alternative to the typical 4-driver passenger engines of the era (such as 4-4-2s), which were fast but lacked the power to pull heavy trains. The only problem I see with this design is that unless it was meticulously maintained and oiled, all those shafts and gears could cut back on the running speed. So we’re gonna keep it meticulously maintained and oiled.

It'll have the power of a small 8 to 12 couple loco with the flexibility of the 4-4-4 you've drawn. Very nice.
Matching the gear ratios to the different driver diameters would take some careful, fiddly math.
As for meticulously maintained: assign it to a small district, like commuter service. Somewhere where it will return to the same shop and shop crew at the end of the day every time. Assign it to a line with steep grades and lots of curves.
