This one relates to the short underpass, that goes under the same railway lines, between Churchill Road / Chapter Road in Willesden Green and Griffen Close / Waterford Way in Dudden Hill. The walls of the underpass are painted black to stop graffiti. But the lighting is poor and is often graffitied over making it darker. This is a well-used pedestrian route but people are deterred using it because of safety concerns. Can you please confirm who is responsible for the upkeep of this underpass - is it TFL or Network Rail? Can you please advise how we can get the responsible body to undertake the necessary improvements?
