The £50m changes to Finsbury Park station have come under fire from the Liberal Democrats who claim the consultation was not good enough.

Haringey Lib Dems are calling for a new consultation for residents to “have a say on changes that will affect their daily commute”.

The busy station is set for a multimillion-pound makeover aimed at reducing congestion and meeting the demands of the Victoria line.

But campaigners are asking Transport for London (TfL) to consult more widely with users amid concerns the Wells Terrace entrance used by Stroud Green residents would be closed.

Ben Myring, a Lib Dem candidate for Stroud Green in the coming council elections, said: “I regularly use Finsbury Park station and it is extremely overcrowded at rush hour, so it is great news that improvements are going to be made. But TfL need to do a much better job of communicating with local people and explaining their plans.

“There could be months or years where the station only has two entrances, causing massive disruption.

“Residents pay a lot of money to travel on the Tube and should have a say on changes that will affect their daily commute.”

When the changes were announced, a spokesman for Finsbury Park Trust said: “It’s going to be easier for commuters, and we’ve finally got the step-free access that we’ve been campaigning for for years. They’ll double the capacity for commuters and ease congestion, and the access will really improve things. I’m really pleased with the recommendations.

“That and the spiral staircase are two major improvements that we’ve been wanting for years. It’s one of the busiest stations in London after King’s Cross.”

The interchange, which hosts National Rail services and both the Victoria and Piccadilly Tube lines, will get a new spiral staircase as well as new gates and a “major commercial development”.

The station opened in 1861 and was home to the first Piccadilly line services between the station and Hammersmith. The line now has more than 176 million users per year.
