I saw on TCS's web page this morning that they have designed a new decoder that help you out when you have bad track. These new decoders, KAT1 and KAT2, will have Keep Alive Technology (hence KAT) in them. Basically if your engine hits a dead spot in the track, it will run for 5-15 seconds before stopping. I watched the demo and it doesn't even slow down and the lights don't dim on the dead track. http://www.tcsdcc.com/public_html/Customer_Content/Web_Tools/Videos/Main.html Ethan
