It doesnt seems fixed. Also there are some more strange things happening in the savegame. Following the instructions underneath demonstrates that:
Using my savegame in first post to demonstrate:
Hold the view at "Debingborough Railway Station", with the passenger train [(46) LBSCR Small Single 2-2-2] waiting.
Fast forward to time: 1874 May 2:44:46, and the good train [(57) LBSCR Standard Goods Engine 0-6-0] will enter the station.
Wait until the good train has loaded (around 7 min)
When it has loaded, the good train will also show [waiting for clearance].
A number of things:
1 - The initial bug: the passenger train wont get the clearance.
2 - The good train [(57) LBSCR Standard Goods Engine 0-6-0] tries to reverse backwards out of the platform. In the savegame there is wrongly a choose signal pointing out to the main line from the station on the platform the good train holds. It should be a normal signal, but the effect are exactly the same if you put a normal signal there instead of the choose signal (before the train arrives).
Anyway, it should not turn around unless its a sackstation.
3 - The good train reserves the track through multiple end of choose signs until the choose signal at its next stop in the schedule.
