I've been having a heck of a time adding engines to the remote, not a new problem and have always had problems with adding engines to the DCS remote on past layouts. This layout is a 4x8. Two unconnected loops with one loop having two sidings. Power is provided with 2 MTH Z1Ks DCS is V4.01. Proto2 and Proto3 engines have difficulty. All Proto2 engines have BCRs. Someones does it only take 2 attempts to get engines to add, sometimes about half a dozen or more.
I picked up a number of engines from repair. Ran fine for my repairman after repair, ran fine on my LHS layout (all under DCS loading into respective remotes instantly) and run fine AFTER struggling to add engines. DCS Signal is 10s all the way around. Track is clean. It should not be so difficult to add an engine on such a basic layout. Any ideas for getting it to work reliably all of the time? Not looking for temporary fixes.
