Changes are planned for the entrances and exits of an overground station.

From Wednesday June 13, new ticket barriers will be introduced at Highams Park Overground, while the subway entrance/exit on platform two will be closed.

All passengers will have to enter or leave the station via platform one crossing the footbridge, but the subway entrance/exit will still be available in the event of an emergency and the station will remain fully accessible with step-free access to both platforms.

The changes are part of the upgrade to stations on the West Anglia routes of London Overground. These routes include services from Cheshunt, Chingford and Enfield Town into Liverpool Street station.

Rory O’Neill, general manager of London Overground, said: “Since London Overground took control of West Anglia services in 2015, thousands of Londoners have benefitted from an improved, and more integrated, train service. The installation of CCTV, modern lighting and help points across the line has improved safety for all passengers.

“We have also introduced modern ticket machines and a ‘turn up and go’ service for those with reduced mobility. Installing automatic gate lines at Highams Park will help protect our paying passengers from those who avoid paying a full fare for their travel.

“This represents a further important step in improving London Overground services, with new, longer, air-conditioned trains to be introduced on the line.”

TfL is strict on fare dodging, penalties include fines and being charged a maximum fare.

These penalties has seen fare evasion slashed to just two per cent of rail and bus journeys with TfL, which is low compared to other transport authorities around the world.

TfL said that safety and security of passengers remains their top priority and all stations along the route will continue to be staffed at all times while the trains are running, with station staff encouraged to offer help to anyone who looks as though they may need assistance.

A TfL spokesman added that the company continues to work closely with policing partners to tackle crime and antisocial behaviour.

Gate lines have also been installed at Wood Street Overground station where the secondary entrance has now been closed. Passengers are required to enter/exit the station through the Upper Walthamstow Road main entrance.
