Ancient Poole Farish 0-6-0 GP tank (?) chassis, which in theory might make a good power bogie for a C-C 3mm scale loco (10.5mm gauge.) Wheelbase (31.75mm), and wheel diameter (8.9mm) just right. Sturdy looking, with metal worm and gear on centre axle.
Problem - need to remove the drive rods, which power the inboard and outboard axles. Once you do that, chassis is only powered on the centre axle, which would be pulling one axle and pushing the other. Doesn't sound ideal.
Looks hard to modify, without a lot of surgery plus a new motor with new shafts, and I'd have to harvest another geared axle from another loco. I also wonder whether the worm is a special design as it is inclined, as you can see motor and shaft are tilted down at an angle. Maybe someone out there has done it?
Wondering if anyone's ever tried to use a pair of them as power trucks as they are, and how they performed? Two axles powered on a C-C loco is not unknown in older N scale. But usually that would be powered front & centre axles on one truck, with the other free truck rolling.
In this case there would be two swivelling trucks with centre axle powered on each. Loco would not be expected to move faster than a scale 40mph or pull more than ten bogie wagons.
Hmmm, work or not work ?
