Major upgrade work is taking place at Whitechapel as the station prepares to become a new modern transport hub with the arrival of Crossrail services.
The addition of Crossrail services in 2018 will be a huge boost for the area with up to 24 trains an hour carrying up to 1,500 passengers between Paddington and Whitechapel in peak times.
This will provide passengers with a frequent service to Heathrow, the West End and Canary Wharf, radically reducing journey times and boosting jobs and the local economy.
A significant amount of work has already taken place at Whitechapel to rebuild the station and create new tunnels for Crossrail, but while much of the work has been undertaken without any disruption to the London Overground, some service suspensions are now required to install a new concourse directly above London Overground tracks.
This will mean services on parts of the London Overground East London line will not operate from Saturday 25 July to Tuesday 28 July and Saturday 1 August to Sunday 2 August.
Transport for London (TfL) will also take this opportunity to complete signalling works along the East London line, as part of its £320m programme to boost capacity on London Overground - giving Whitechapel residents better, more comfortable journeys.
Mike Stubbs, TfL's Director of London Overground, said: `We have worked closely with our colleagues at Crossrail Limited to ensure that the work impacts on as few journeys as possible and take place during a quieter period on the network, when the schools are on their summer break. We are also taking this opportunity to complete our own signalling works, continuing our drive to minimise the impact of closures and keep disruption to our passengers to an absolute minimum.'
Simon Wright, Crossrail Programme Director, said: `Crossrail's works at Whitechapel will result in a brand new station providing step free access to, and between, Crossrail, London Overground and the District and Hammersmith and City lines. The centrepiece of the station will be the new pedestrian concourse alongside which will run a new pedestrian route between Whitechapel Road and Durward Street. The construction of the pedestrian concourse includes the installation of steel sections on which the floor of the concourse will be built. Due to the location of the new concourse these can only be installed when London Overground services are not running.'
