N Scale BEMF Decoders

BEMF and N Scale. N scale has always presented a challenge in the area of motor control due to the small size of the motor and flywheels. All this has changed with the introduction of TCS's new BEMF (BEMF = Back EMF / Load Compensation programming, built into the new TCS chips) which compensates for the small size of N motors/flywheels. TCS BEMF provides outstanding slow speed control for N. TCS's new advanced BEMF automatically adjusts for optimum control through all speed ranges.
New CN Classic Decoder has been designed to fit inside the Atlas RS series of locos. Two small boards connected by wire (factory connected) replace the "headlight" PC boards on each end of the OEM frame. You need to "isolate" the motor and solder a wire attachment ... that's it. The result is a full function DCC loco (all the features of TCS's regular decoders) plus the added performance benefits of the new BEMF control. If you click on the PC board photos above, TCS shows complete install details on this simple conversion. Highly recommended. Your classic Atlas RS series of locos have never un so well! We expect that this new decoder will also fit other split frame N scale locos.
