I bypassed the TIU with a cutoff switch that isolated the layout till after the watchdog signal went out. The PS3 SD70 started up and ran in conventional mode, as as well as the PS2 Dash-8. Both locos performed an extended shutdown after power was removed, after moving back and forth for less than a minute each.
I did have to wiggle the SD70 a little to get it to start up at first (a K-Line voltmeter car coupled to it confirms the track isn't spotless, then again it has only one pickup roller), but it had no trouble moving over that same stretch of track once running.
With the SD70 idling, I attempted to access it thru the remote (start-up) and received the same 'Check Track', Engine Not on Track' messages. I'm starting to wonder if my TIU is getting flaky in some manner. How old is Revision 13B again?
(I have a newer DCS kit that I had been using at "first night" train displays I used to help out with, I may have to dig it out and try a swap)
