Recently from time to time I observe a comparable behavior of 3 dedicated Legacy equiped diesel engines during operation on my layout. These engines have the newer smaller electronics on board.
I have identified four spots on my layout where for these engines the signal can be disturbed. Already set earth ground lines do not help. The engines will stop or do not start proper at these locations. All these spots are in the neighborhood of
-electronic devices such as SC-2 or Märklin-Decoders(I operate that system for
switches) or Miller Engineering power pupport for Illumination of the signs.
-a collection of transformers to feed the layout.
About the reasons I can assume only.In 5 years of Legacy Operation I had only one such Event several years ago. But recently I observed that several times.
We have since some weeks in the house the power lines in use for data transmission between both a router and PC and a computer that is allocated to a solar power station on the roof. I have observed already that during heavy data traffic for communication between the router and the computer the 3 engines are out of control. But that is until now only a not waterprooved assumption
I made a trial. In such an area I raised an already existing earth ground wire about 2 inches above rail level and then the engine worked again flawless during such an event. Otherwise, when I observe this stop and go repeatedly at the defined Locations, I remove these engines from the layout for the Moment.
By the way, with MTH-DCS I had already engines that ran out of control in such a situation, so I had to switch off the layout.
As a conclusion:
-I´ll try to replace the receiver at these engines, as not all engines show this behavior
-in addition I´ll check whether the antenna is not proper connected or insulated.
