TICKET office opening hours on Tube services will be slashed from Sunday, with Harrow being particularly badly hit.

Seven stations will close their afternoon and evening ticket office, while reduced off-peak hours apply to nearly all stations in the area.

Northwick Park is one of the stations worst affected, with opening hours reduced from 6.15am – 7.30pm to two peak-time periods of 7.30am – 10.15am and 3.30pm – 6.15pm.

Howard Collins, chief operating officer of London Underground, said: “The success of Oyster has meant that the number of customers who use the ticket offices has declined sharply, and people are increasingly using ticket machines, the web, and automatic top-ups.

“We have made the commitment that our high safety standards will be retained - every station will remain staffed, and that every station with a ticket office will still have one with opening times that reflect demand. Staff who were previously behind under-used ticket office windows will be able to be deployed to places where they can better assist passengers.”

The changes to hours go ahead despite a number of strikes over the issue by Underground workers since Mayor of London Boris Johnson announced the plans last March.

A source at the Transport Salaried Staffs' Association trade union said: “The passengers and staff at London Underground stations will always be opposed to these cuts and continued attacks on ticket offices and the services they provide, which go far beyond just selling Oyster cards.

“Through the pressure on political representatives we did manage to the stop some of the changes.”
