Ahh engineering works, a constant battle
Ive checked the National Rail website and it does indeed state “Trains between East Croydon / Clapham Junction and Watford Junction will not run.” However, all is not lost! We can still get trains to either London Bridge or London Blackfriars. From there we get on the Northern Line to Battersea Power Station. It will take a bit longer given there is a reduced service but still doable. For that reason Im still happy to go along but understand if others want to have a re-think.
