Yesterday, my N Scale Bachmann RS3 ran away. The only way I could stop it was to turn the power off to the track. Fortunately my Digitrax Zephyr has a button for that. Unfortunately, when I turned the power on, the loco was dead. Now I have two feelings about this. One is that, having told the wife that I didn't need anything else for the railroad, I now have to admit to needing a new decoder. The second is pleasure that I am replacing the decoder as the built in Bachman decoder is quite limited and the loco never ran very well.
As you can't get a drop in board for this loco, I am looking at the TCS M1 Miniature decoder - details here: http://bit.ly/XashQm.
Kevin at Coastal DCC has these in stock so I should be back and running with it soon.
