[quote user="rrinker"]  It's not that DCC is more finicky, it's that the voltage on the rails in DC directly controls the speed, so if there is a slow and gradual voltage drop, you don't see it and/or automatically compensate by turning the speed control up a bit. I ran an 8x12 double track layout with DCC on one pair of feeders as well, no problems. Hooking up all the rest of the feeder drops didn't change things, either. There's nothing more finickey about DCC, as long as the voltage remains above the specified minimum there should not be any control issue - and it takes a LOT of nickle silver rail and/or a huge load of powered equipment to cause the voltage to drop from the nominal output at the main booster to a level below the NMRA specifications.  At the same time, I had a basic 4x8 oval of Bachmann EZ Track running on DC and the locos noticeably slowed at the furthest point from the power pack. I had to add extra feeders to fix this. Being sectional track, thre were more joints in this 4x8 oval then there were in the 8x12. This is the real cause of issues over long track runs with few feeders.  That 8x12 also ran in a basement with open ceiling joists and unfinished poured concrete walls and floor. Outside of cleanup after painting the rails, I didn't clean the track on that one, either. Just a light brushing to remove loose dust on occasion. No liquids, no abrasives. I still contend that anything that STAYS wet on the rails only makes it worse.                                  --Randy <div style="clear:both;"> </div> [/quote] Did a quarter trip the DCC circuit breaker prior to adding additional feeders?
