This full featured 4 function BEMF decoder is for the N-Scale Intermountain F3A/B, F7A/B and F9B locomotives. Included is our auto-adjusting BEMF for outstanding slow speed performance and hassle free set up. Also includes Quiet Drive for super quiet engine performance.
NOTE: This version of the IMF4 is designed for the newer style Intermountain frame where the motor is connected to the control board via soldering wires not the previous style of using “Motor Feet”.
COVID-19 INFO: Arizona has issued an ordinance for us to shelter in place through the end of April. Orders will be accepted and processed, hopefully, with no change in service. Thank you for your patience! Dismiss
