Passengers using West Hampstead’s Overground station could face delays from Sunday with work set to start.

The refurbishment will include twice as many ticket gates, a larger concourse and step-free access between the street and the platform.

The changes are in response to a projected increase in passengers.

Access to the platforms will be changed, and passengers will have to use a temporary walkway that will link to a recently finished footbridge.

An additional temporary station entrance will also open a few metres away from the current main entrance during peak hours on Monday to Friday.

A Transport for London spokesman said: “The work meets objectives of the Mayor’s Transport Strategy, which aims to create a fairer, greener, healthier and more prosperous city by improving public transport and reducing reliance on car journeys.

“It will make life easier for older and disabled people and give a greater choice of travel options for everyone, and directly benefit parents and carers with children and buggies.”
