Is there anything special about wiring a double crossover (i.e., "X") for DCC? I am building a modified version of the Salt Lake Route layout that was in MRR back in 2010 except using primarily Code 55 flex track instead of Kato. I built the crossover using the parts list and information from a link I found on this site (since Atlas does not offer a double crossover), but it did not mention any special wiring to prevent short circuits. I am not doing any loop backs on my layout and my main lines are to be in parallel. Thanks!
