Train likely to be the transport of choice for many, although I guess that as some will have work the next day it might reduce the drinking factor a bit.
Although it's worth saying that as it is a Bank Holiday Monday, there's an increased chance of there being engineering works scheduled. Presumably a slightly reduced (Sunday service?) timetable too.
Timetabled works are only listed up until the beginning of May as it stands.
Great for the club to do this and also, I'm sure, great for the lads who get to represent the Albion - getting to use the home dressing room and play on the sacred turf.
Presumably there will be a fair few ball boys/girls deployed around The Amex as I'm guessing just one stand will be open...
