Having actually done some of these exact conversions on the same type of locomotive, I have to disagree with a couple of opinions. They don't appear to have the torque of the Pulmore motor, remember that Timko uses the Mabuchi 3xx motor, a fairly small motor. The gearing is very tall, I don't remember the gear ratio, but it's not as large a ratio as modern diesels and doesn't have the low end torque. I'm sure someone with a similar engine in captivity could probably easily measure the gear ration and clue us in. Also, the can motor is much lighter, so you have to add considerable weight to the engine at the motor end to even have the traction to the rails the same as the old Pulmore.
