From a timetable "commencing 22nd May 2011".
UPDATE: This from The Sleeper...
That's all due to the fact that Berney Arms is the only open station on the National Rail Network with no lights, since it's one oil light was put out in 1970.
So in BST the evening train runs but in GMT it is too dark.
Eye notes with comfort that this part of Norfolk still appears to be on the Julian calender.
UPDATE: This from Connor...
Berney Arms isn't quite the only station on the National Rail network without platform lighting.
Coombe Junction in deepest, darkest Cornwall also has that honour. It doesn't get anything as fancy as a different timed train each day though.
The evening service was simply moved to one hour after the morning one a couple of years ago, after being cancelled everyday for 6 months of the year for many years before that.
