I'm coming to the conclusion that Ely ticket office now shuts at 09:30 in the morning. For the last two months, I've travelled on either the 09:16 or 09:48 Great Northern trains. Without fail, when I arrive at the station a few minutes before the 09:16, the ticket office has been open. But a few minutes before 09:48: it's always been closed.
Now that I've made this observation in pubic, I fully expect the next time I travel to be a counterexample
