The Chuff-Generator (C-G) is an add-on electronic module for TMCC controlled steam locomotives to replace mechanical chuff switches. It also supplies a programmable chuff rate locked to driver rotation
The C-G can be installed in factory TMCC locomotives or TMCC upgraded locomotives. This is a microprocessor based design that allows for software updates to accommodate functional changes and possible future enhancements. The C-G is mounted on the motor and reads a tach tape on the flywheel to measure relative distance and determine relative speed. An optional output for ground light control is provided; the ground lights will be extinguished at approximately 10 MPH and lit at other times. The MPH calculation is based on an average gear ratio and driver diameter and may vary between models. The C-G is fabricated on a printed circuit board with the dimensions of 1.3" x 0.4" in size. The overall height including components is approximately 0.125".

We perform a lot of Electric Railroad upgrades. I installed the Chuff Generator with a Supper Chuffer that was supplied by the customer in his locomotive with a Cruise Commander and Sounds. It works great. This is a nice upgrade to any engine with a DC can motor with a flywheel and a fan driven smoke unit. It is not difficult to install. I highly recommend the kits.
