With the arrival of Crossrail services scheduled from 2019, with the associated enhanced travel opportunities and improved regional connectivity, the accessibility and quality of facilities at and around the borough’s three stations will become even more crucial. Langley Station will be a gateway for Crossrail within Slough, providing rail access and connectivity between the residential areas in the east of the Borough with both the wider Thames Valley Berkshire sub-region and London. The Langley Station and Access Improvement scheme is expected to support the Thames Valley Berkshire Local Enterprise Partnership (TVBLEP) aims of investing in infrastructure that would help grow employment, enterprise and industrial opportunities in the sub-region and enhance cross-boundary connectivity. The Core Scheme aims to improve pedestrian and cyclist access to Langley Station, provide reconfigured parking arrangements and drop-off facility for the station, and improve the perception of safety and security at and around the station. This includes measures such as new provisions and improvements of pedestrian facilities, introduction of shared use areas for pedestrians and cyclists, improvement of cycling facilities both within and around the station, reconfiguration of station car park including a new drop-off (kiss-and-ride) area in the station forecourt, and improvement in the landscaping around the station as well as the public realm. The scheme will also include elements undertaken by Crossrail/Rail for London under their On-Station Improvement Programme Step Free Access scheme. Problems and objectives The Langley Station and Access Improvement scheme would provide an opportunity to improve pedestrian and cycling access to and around the station, thereby encouraging increased walking and cycling trips. Improving access and safety at and around Langley Station would improve the attractiveness of Langley Station, and therefore support the TVBLEP aims of investing in infrastructure that would unlock future opportunities to enhance cross-boundary partnerships. The Langley Station and Access Improvement scheme’s public realm enhancements are expected to widen the influence of the Heart of Slough regeneration within Slough town centre, as well as wider infrastructure improvement projects within the town. The improvements to the station facilities, including a lift, wider stairs, minor station refurbishment works, and modified platform furniture will enhance perceptions and safety at this station. The Langley Station and Access Improvements scheme would ensure users with reduced mobility will be able to use the new rail services serving Langley Station. These users are currently unable to access existing services to and from the station, with the current layout necessitating that they travel to Slough or Datchet stations at present. Generally improving connectivity from Langley Station would contribute to improving people’s ability to access employment and education opportunities. Public realm improvements will also support local affordable transport in order to reach these opportunities, especially for pedestrians and cyclists. vi Atkins Business Case | Version 1.3 | 8 November 2016 | 5149496 Langley Station and Access Improvements Business Case Objectives Desired outcomes (1) Improve Facilitate / encourage commuter travel to/from Langley station pedestrian Encourage mode shift for journeys to/from the station towards sustainable access to and active travel Langley Enhance the legibility and visibility of Langley station to residents and station commuters in the wider area Improve safety and journey times for pedestrians using the key Station Road / Waterside Drive junction Maximise benefits accruing from rail operator investment into improving the services and passenger facilities at Langley station Transform the area around the station to a less car-dominated
