Commuters struggling with a cramped commute on the Victoria line will see a boost from today, after Transport for London (TfL) doubled its peak time service.

At busy times on weekday mornings and evenings trains run every 100 seconds on the line – and now that peak period has been extended from an hour and a half to three hours.

Outside peak hours, trains run just less than once every two minutes.

Previously, Victoria line peak time ran from 8.15am to 9.45am and from 5pm to 6.30pm.

But today’s increase will see a more frequent service run from 7.15am to 10.15am and from 4.15pm till 7.15pm.

More than 250 million passengers use the line each year, and it serves some of the Underground’s busiest stations, including King’s Cross, Oxford Circus and Victoria.

Mayor of London Sadiq Khan said: “The Victoria line is one of London’s busiest Tube lines, so I’m delighted that our new timetable will mean hundreds of thousands of commuters will benefit from quicker, more comfortable journeys.

“Since becoming Mayor I’ve frozen TfL fares, introduced the Hopper fare and invested record amounts in new infrastructure – making it even more convenient for Londoners to use public transport.”
