Indeed - there should be a notice at Berney Arms station informing passengers what to do if the train doesn't turn up.
After all someone who has paid for a ticket has a contract with the train company to be conveyed to their destination (not necessarily on time, or by train)
I seem to recall that some stations on the Settle - Carlisle line have a help point that is connected to the signal box.
So perhaps the help point at Berney Arms needs to be re-routed to someone who is able to help out.
After all there is vehicular access (albeit down a private road) to the pub (otherwise how would the beer get delivered) so it wouldn't be impossible for the TOC to order a taxi from Great Yarmouth and send it down there to pick up anyone who is stranded by a cancellation.
