The reason I say this is because I had Trainz Plus beta build 123315 installed. When I started it up today it automatically asked me if I wanted to update. I said yes and it automatically installed Trainz Plus build 123794.Well, all I can say is that 123794 is showing on MyTrainz downloads as the "TRAINZ PLUS EDITION"
When I started up my Trainz Plus build 122411 there was no notice of an update. So, I checked for a Trainz update. The message I received is "No update for Trainz is available at the current time". My conclusion is that build 123794 is still a beta version.
