Barking Riverside Extension – Factsheet C Viaduct Proposed route alignment Transport for London (TfL) is proposing a 4km extension (1.5km of new track) of the London Overground Gospel Oak to Barking line to Barking Riverside. The service would operate from Gospel Oak along the existing route to Barking before crossing the London Underground and National Rail lines west of Barking station. It would use the existing grade separated flyover, (currently used by freight services to access the Tilbury line from the Gospel Oak to Barking line), to serve platforms 7 and 8 at Barking station. Eastbound services from Barking would continue for just over 2km along the Tilbury line, used by freight and by c2c services operating between Fenchurch Street and Grays. Services would then spur to a new section of railway approximately 180m to the west of Renwick Road, before continuing east under Renwick Road Bridge. At this point the alignment would climb on a viaduct at a gradient of 2.5 per cent curving south towards Barking Riverside. As the alignment crosses the freight terminal, westbound Tilbury lines, and Choats Road the viaduct would reach a height of 10.5m. It would then descend to a height of 3.5m to pass under the existing high voltage power line south of Choats Road. The alignment would then ascend and continue towards a station at Barking Riverside, which would lie 7.5m above ground level. The westbound line from Barking Riverside would run in parallel along the viaduct as far as Renwick Road. It would then continue along the track alignment of the former westbound Tilbury freight line, merging with the westbound Tilbury passenger line, approximately 500m east of Barking station. An overview of the proposed alignment is presented in Figure 1 on page 3. Viaduct design The viaduct would comprise of pre-cast beams spanning 25m which the new railway would sit upon. The beams would be connected using a concrete deck and supported by reinforced concrete piers, which would have a construction depth of approximately 2.3m. Figure 2 on page 4 illustrates a view of the proposed viaduct from the junction of Keel Close and Choats Road. Barking Riverside Extension alignment and surrounding development To the west of the proposed Barking Riverside Extension (BRE) viaduct, is a cluster of residential properties located in the Choats Road and Great Fleete Way area. The BRE alignment would be more than 85m from the nearest house, with most properties located more than 100m from the alignment. Figure 3 on page 5 presents a summary of the distances between the proposed BRE alignment and nearby properties. 1 The BRE alignment would be located to the west of the Barking Riverside site and would run in parallel to the existing high voltage power cable alignment. This would maximise the use of space by the pylons, which would have limited value for other purposes and land uses. The viaduct on which the BRE would run would maintain east-west access across the site and would ensure vehicle access under the viaduct at points required as part of the Barking Riverside development plans. Next steps The project will be subject to Environmental Impact Assessment (EIA) under the Transport and Works (Applications and Objections Procedure) (England and Wales) Rules 2006). The environmental assessment process will ensure that the environmental effects of the proposals are properly considered in the decision making process and also as part of the engineering design process. The Transport and Works Act Order application will be accompanied by a full environmental statement.
