My 44 tonner is one of the more important locomotives on my layout. unlike the others, which get switched out occaisionally, it is ALWAYS on the layout, because its the only one that fits in the space its assigned to. it was already loud, but i haven't run it much until just yesterday, when I installed a DZ123 decoder into it. It runs, but its will not creep at all, and even at speed step 1 (on 128 speed steps) it moves faster then i'd like it to. I know this engine can creep on DC, but on the DCC it seems faster. could i possibly find a way to lower the speeds involved via the decoder? Or do you think a little extra cleaning and work will do the trick for it?
