DCC and Bachmann Spectrum 4-8-2

I have some experience with one of those locos. I installed a Lenz Decoder in one of them for a friend of mine.
The loco is very low geared (very nice slow speed and it still runs prototypically "slow" even at full throttle).
But it's fussy as far as electrical pickup goes. Strange as both the tender and the loco itself pickup current.
So, you need to keep you track perfectly clean to make that loco "happy".
I installed the Lenz decoder because it is the smallest N/Z decoder available. But personally I don't like Lenz decoders because they seem to need to reset after each power interruption. That takes about a second. So, every time loco loses contact with the track, it sits for a second until it starts up again. It is quite annoying.
Digitrax decoders dont' seem to have that problem. They start running almost instantly after they power is interrupted. But they are a bit bigger than Lenz. And Lenz fit in that loco perfectly.
That is pretty much all I know about this subject.

Thanks a lot for your information. I'm getting the decoder, a Lentz, installed by the shop I'm buying it from. I hope to get started on the test track next weekend, conventional power first then DCC by Christmas. With luck I can start on the layout itself early next year.
Thanks again Richard
