Moose: Obviously the bad locomotive is total junk. In order to save you any additional aggravation, you should box it up, send it to me, and just forget it ever existed.
@JMaurer1 Ummm, yyyyy-no... Moose pull out a Kato F3, w/ MRC 1957 DCC Sound decoder, cleaned the wheels, ran around the layout just fine. Put 'er up on the roller test stand, and tap the loco, stutter and stop, tap the loco, stutter and stop. How rude! Mrs Moose come up with solution, applying some weight and she (the loco, not Mrs Moose) ran smoothly on the rollers!
Regardless of order, I recommend neither applying the Martini to the track, nor eating the Brite Boy. However, the correct practice/application of each may be easier to follow if you use the Brite Boy on the track before you drink the Martini. But then again, if you drink the Martini first, then all you have left to clean the track is the Bright Boy.
Just to be clear, the weight was applied to the Loco, not Mrs Moose? Then the loco, not Mrs Moose, ran smoothly? Wait, are you saying that Mrs Moose does not run smoothly?! Wow, this is quite a minefield you've laid!
Moose appears to be getting his hooves into some deep pucky! As for yout T-1, mine pulled the same stunt. After copious research on a few forums and reviews, I have come to the conclusion that a new and better decoder is what is required primarily. A keep alive memory capacitior will also help. It is sitting aside awaiting my finding time and energy to do the swap over. It is a shame that such a beautiful loco needs to have such a mod to be viable, but so it is. Back to more wake me up java! Before track cleaning and such!
Moose: Take all of your locomotives, box them up and send them to me. I'll take the time to test and tune and send back all the locomotives that don't have problems...if any
