That cured it, thanks!
Oddly, my one engine that I originally noticed it with still doesn't update, the 6-84268 SD40. It triggers the sensor since it does the crossing signal as it goes over it, but it doesn't load it's info. Where is that stored, in the RCMC? It puzzles me how it could trigger the crossing signal and not be transmitting the engine data.
The good news is all the other engines worked.
