Hi, The scenario 'Divergent' is now the third piece of broken/bugged one on the Cathcart Line. There's an AI train (which is the same bug on the 'Around and Around' scenario) which is stuck at the station on the return journey. The players train is stuck in the sidings, unable to move due to the red signal. The signal is red because the AI train is blocking the line. I'm unable to move the AI train. I've submitted a ticket along with these screenshots. Hopefully one day this DLC/route will be fixed. Thank you Player train. AI train stuck at the platform. Map view.
Are you playing from a loaded savegame? Doing that is almost guaranteed to do what you're describing.
This has been broken since the 4.26 Rush Hour update. Matt mentioned on a stream last week it is a knock-on effect of trying to fix an issue where AI trains were SPADing and is affecting lots of routes. The good news is he said that a fix was is testing so hopefully won't be too long before it's released.
