Works at Walthamstow will allow 36 trains per hour service
The northern section of the Victoria Line will be closed for three weeks in August as London Underground works to raise capacity on the line.
Services will be suspended between Seven Sisters and Walthamstow Central from 8 August to 30 August while LU carries out work to rebuild the crossover outside Walthamstow Central station.
The crossover currently limits the number of trains which can run north of Seven Sisters to 24 per hour, but the work will allow LU to run 36 trains per hour along the whole line. LU says this frequency, which will provide a train every 100 seconds in peak hours, will make the Victoria Line the highest frequency railway in the UK.
During the closure services between Seven Sisters and Brixton will run as normal, although with a slightly lower frequency. Rail replacement buses will be provided between Walthamstow Central and Seven Sisters as well as from Walthamstow Central to Stratford and from Chingford Mount to Seven Sisters.
