A petition was signed by over 200 people who are demanding the filthy approach to Willesden Junction station is cleaned up.
Residents say they are sick of the dilapidated state of the road, the ownership of which had long been disputed.
After a Chronicle investigation last month, it was established the land, which falls in the borough of Hammersmith and Fulham, is the responsibility of the Network Rail.
And last week, a group of residents, led by the Keep Harlesden Clean group, clubbed together to crank up the pressure on Network Rail by gathering signatures. They will present the petition to the council.
Keep Harlesden Clean's Hayley Borg said:"Willesden Junction has been a thorn in many residents’ eyes for a long time. There is rubbish everywhere on the embankment, the road is falling apart, and so is the pavement. It is unsafe, looks awful and is just not a very welcoming environment.
"Brent council, with the help of an outside organisation and residents of the area, is currently developing a vision for Harlesden and we believe Willesden Junction must be part of this vision. Something must be done sooner rather than later. Network Rail should not be allowed to get away with this once again. Harlesden just deserves better."
Network Rail pledged to take action on the site in the future.
