It seems there will be no issues on my journey as I’ll be travelling into Clapham Junction via the South Western Rail network and there don’t seem to be any problems on the short onward hop to Battersea Park via the Southern Rail network. So hopefully, I’ll meet you all at Battersea Park Station, at around 3:30pm.
FYI – The forecast suggests that although it’ll be quite cloudy and cold (circa 6-7 degrees) on Sunday afternoon, the likelihood of rain is less than 10%. So dress up warm!
