Plans to create step-free access at Croxley Station were drawn up almost three years ago

Hertfordshire County Council and Transport for London examined six different options for creating step-free access at the Watford Road station in April 2013.

The report went as far as suggesting that a ramp could be built between the car park and the southbound platform and a lift could be installed to the northbound platform.

A shaft for a lift was built in the station but one was never installed and the report suggests this is the best way of providing access to the northbound platform.

But TFL has not confirmed when step-free access will be installed at the station.

In its conclusion, the report said step-free access could be created in six to nine months and would have “minimal impact” on trains running from the station.

The documents obtained through a Freedom of Information request do not reveal the cost of the six schemes.

Disabled people, elderly people and parents with young children all complain about getting up and down the 40 stairs at the station.

Cllr Peter Getkahn, who has been campaigning for step-free access at the station, said: “I find it strange that Herts County Council and TFL dumped this idea after such an impressive consultation document was produced.

“It is clear that step-free access could be up and running within 6 months with little or no disruption to the running of the service.

“The residents of Croxley are going to experience the bulk of disruption whilst the rail-link is being built, so it's only fair that everyone in the community has access to it when it's finished. TFL have done the ground-work, and I hope they finish the job.”

More than 700 people have signed a petition calling for the changes to be made as part of the Metropolitan Line Extension, previously known as the Croxley Rail Link.
