The current system is a bit inflexible in chaos scenarios. I just did the run with the Voyager from Plymouth in the snow that ends up terminating at Newton Abbot. But despite that, the announcer was still stating the next station was Exeter SD and the train was going to Leeds. Would have been better if the text pop up showing a message from the driver to the passengers (which would have been made by the Guard) had been fed into the announcement system instead, together with the platform announcements stating all change.
For some reason, the passenger ambience in the Class 150 isn't working. I've ensured that the settings are enabled, but even while walking through a completely full train, no sounds are playing. I noticed this issue after the most recent update on Steam. I searched for a feedback thread regarding passenger ambience but couldn't find one, so I'm sharing this feedback here.
Announcements (Voyager) refer to Newcastle as Newcastle Central. Pretty sure this is wrong, should only say Newcastle.
