For several years I have been using DCC decoders from Lenz or some locally
made brand; both working pretty well. Recently I bought sound decoders (from
Sountraxx). Sound is great, BUT pretty soon I found that they are very
sensitive to dirt on the track: even the slightest dirt brings the engine to
a stop and then restart (or stay idle if the dirt is larger). Things are
worst with a long acceleration rate (CV 3). Am I the only one to notice
I just installed a MRC Brilliance in a Stewart F unit, works well but
there are occasional points where there is a slight loss of momentum
then it picks up again. Maybe a good indicator of track that needs
cleaning or other maintenance. Roger Aultman
Yeppie, dirt is the enemy of the DCC system! You need to have a good
contact with the rails in order to have good trouble free operation. Of
course, this is true of any control system but the DCC system can have more
problems than ordinary DC does.
Cleaning track does help with the problem as well as keeping the layout
room clean with an air filter. Also helpful is to use contact shoes
although this does make you clean up your trackwork a lot.
