The handcar has a DC can motor. There is a small rectifier with the AC leads soldered to the frame and pickup. The DC leads then go to the motor. I removed the rectifier.
The ballast tamper had a rectifier in it, which I installed from a kit. The kit converted the AC/DC motor (universal) to a DC motor.
Here are the instructions that came with it, 20 years ago.
For $11.95, I got a rectifier and the instructions. But, I did learn how to make the conversion, and, the store owner told me how to make a converter for the transformer.
I used the largest rectifier sold at the Shack and a capacitor. The AC leads go to the transformer and the DC leads go to the track. The capacitor bridges the DC leads and helps boost the voltage.
A DPDT switch then is used between the AC/DC converter and the track to change the direction of travel.
BTW, I'm careful not to run the ballast tamper in reverse while in "tamping" mode. There are cams which would destroy the tamper action. For this reason, I did not attempt to convert the Burrow.
If you have a layout, you can keep it. If you have locomotives, you can keep them.
I'm having trouble deciding how to spend all of my Obama Care savings.
