I don't have the Turbo Train, so I'm not worried. So far I haven't seen any issues with the speed that the DZ-2500 activates the non-derailing feature. Obviously, the switch isn't instant with the tiny motor, so I see that as a lot more of a risk than the couple of milliseconds the relay takes to do the actual switching of the fixed rails.
Yeah, my speed of the train is pretty extreme to get a short. Grandchild found this one. 😁
Good thing I sent the boards for a prototype run to OSHPark, I had the wrong footprint for the relay! OOPS! I also noticed a couple of spacing issues, but a kludged one together and it works, so I just need to correct the mechanical issues and I'll get a bunch of PCB's.
I need a stiff Bourbon. I completed wiring up a Ross #6 crossover and two Ross #8 curved turnouts last weekend, with the DZ-1008, and screwed the track down. Ordered 4 more DZ-1008s to cover additional turnouts not considered in the earlier order, a week ago. Obviously, this is a vastly superior solution, not only because of the common rail selection but also because it eliminates the dependency on the grossly undersized DZ-1008 relay contact wires (what's the point of a 10A relay with #24 wires connected to it, despite their short length?). At this point, I'll have to try out my inventory of rolling stock to see if I'll have any problems, before I pull things up and rewire (or add ugly visible wires soldered to outside of rails).
