Hi Serge,
Thanks for the confirmation 
Found the issue, the turnout command was not correctly simulated, it was inverted, it is fixed in Build #1929
It was very nice to see the train running automatically, I ran the Lua script while connecting to the simulator, it worked nicely! Did you have to time/possibility to test it on your real layout? If you like, you can share something here.
Greetings,
Reinder
