Hi there Yan, Could you explain how you are going to wire your Power Districts?, I am intrigued by this concept, mainly by the thought that to operate trains, you have to connect each district to a single DCC Controller via a power bus, or run wires from each district back to a single controller, again creating a simple power bus, which effectively negates the separational integrity of each district, since they must all lead back to that single controller. Unless you run only one locomotive at a time, it will be impossible to work out which loco is causing what problems and where.
