The station is in an urban setting with a mix of housing, shops, schools, health and sports facilities. The existing station entrance and ticket hall is located on Whitechapel Road opposite the Royal London Hospital. The station provides access to both the underground and overground rail services. The London Underground (LU) Hammersmith and City and District Lines (HCDL) are aligned east-west. There are residential properties to the north of the HCDL on Durward street and adjoining streets, and to the south along Whitechapel Road. The London Overground (LO - formerly the East London Line) runs north-south in a cutting between the residences of Trinity Hall and Kempton Court. Swanlea School is located to the east of the LO cutting.

Trains from Whitechapel Station will run westwards to Liverpool • Construction of Whitechapel Station Concourses including Street Station or eastwards to either Stratford, or to Canary Wharf. retention of the existing entrance hall, but demolition of the structure to the rear; • Construction of Durward Street Shaft; • Works to HCDL Platforms including refurbishment of the Group Station Manager’s (GSM) building; and • Works to roads and bridges, including replacement of the Durward Street Bridge and demolition of Winthrop Street Bridge. Permanent works at Whitechapel Crossrail at Whitechapel Non-technical Summary of the Whitechapel Environmental Statement Page 3 Passengers will continue to enter the station from Whitechapel Road. The Station Concourses (upper and lower levels) will be suspended above the LO linking the Ticket Hall on Whitechapel Road to Durward Street Shaft, running between Kempton Court and Trinity Hall. A new public walkway will be provided alongside the concourse, providing a safe pedestrian route that people will be able to use without purchasing a ticket. This walkway will improve accessibility for the area and enable people to move freely between Durward Street and Whitechapel Road. The upper concourse will include new ticket barriers and provide simple, naturally lit access to the HCDL or LO platforms by stairs or lift. The lower concourse is then reached via lift and stairs, from where passengers can continue down to the Crossrail platforms. The LO platforms can also be reached from this lower concourse.

The design makes the most of natural light and is of high quality with many sustainable features such as a sedum roof and a green wall adjacent to Swanlea School. A shaft will be constructed on Durward Street and will be located at the northern end of the concourse. This will contain ventilation and safety features. The shaft has been redesigned to reduce the size of the building near the street and to improve its relationship to Swanlea School. View of Trinity Hall, GSM and Durward Street Bridge (Artist’s Impression) View from Kempton Court looking West (Artist’s Impression) The HCDL platforms will receive new canopies, with a number of other adjustments to accommodate the Station Concourses. The Group Station Manager’s building will be refurbished. The Scheme also requires alterations to local roads. Winthrop Street will be permanently stopped up and the bridge removed. Durward Street Bridge will be demolished and rebuilt to accommodate the station concourses and pedestrian access only.
