Ther are some noticications of line closures or delays ... but some live feeds not listing any cancellations / changes at all. And it's the morning of 1st April.
I suspect that our report / diagram at the top is running off a broken feed - in other words, that there are trains cancelled / changed that are not showing. Will follow up as I get more data.
I suggest that live departure boards - e.g.
http://www.livedepartureboards.co.uk/fgw/summary.aspx?T=EXD» for Exeter St Davids
are showing most accurate information
