This problem occurred suddenly. Before that my combined DCS/Legacy/TMCC worked just fine.......But no longer:
1. DCS on MTH engines: Works fine
2. TMCC on TMCC engines: Ditto.
3. DCS on TMCC engines: [Suddenly] VERY POOR. The engine often stops dead; for no apparent reason. It even stops multiple TMCC engines running. This behavior also occurs when given a command such as BLOW HORN, or CHANGE SPEED.
4. A FINAL blow: Unders DCS control, I experienced a MAJOR problem: Several TMCC engines that were on the RR but not powered-up suddenly launched at full speed and crashed! It was as if they were operating under conventional control at full track voltage….
My ad hoc ‘fix’ [temporarily, i hope!] was to disconnect the cable between the Lionel Legacy Base and the associated TIU. Result: A return to items 1 & 2 above. No surprise.
Now I need to determine the root cause of the DCS-on-TMCC engines problem……and I solicit your advice.
