Bob, our club has two MTH locomotives one is an A-B-A F unit and the other a Milwaukee Road Bi-Polar. They respond to programming with Decoder-Pro but have one feature that can't be changed. In order for the sound and lights to be active you must push F3 prior to applying power to the motor. I contacted them and they told me that they would not change that feature. At any rate they run nice but if they stop due to loss of power and then start up again they run silent until you stop and click on F3 and start it again. Hope this helps,
