Revised frame & motor
This is the chassis we are currently using in our production.
Easy sound installation, 21 pin socket for DCC or Sound decoders.
Uses 5 pole motor. This until will not run the same speed as the old
Stewart with the Buehler motors.

Answers to a few questions:
1. The sound chassis will fit Old Stewart Locos.
2. All Units come preprogrammed.
3. As with most sound equipped locos running with DC control, a unit with sound

will start at a slightly higher voltage than a unit without sound

Installation:
Remove old chassis from body and place body on new chassis.
Each unit is track tested and ready to install.
