Brewery Turnback - ES6-8 OLE Infrastructure

Tender description

Brewery Turnback an enhancement scheme funded by the DfT. Formerly known as Manchester Victoria East Turnback, it has been prioritised for early development from the Central Manchester Capacity and Performance study to boost capacity and resilience. The scheme is for the design and delivery of a West facing turnback, located at Brewery Junction. At Victoria station, the through platforms also accommodate terminating trains due to an imbalance of local services to the east and west of the station. The extended time to terminate and turnback in the platforms restricts platform availability for through services. Operational flexibility of the station would be improved if services could utilise a turnback facility to the East of the station. The turnback would also be a service recovery measure during times of perturbation. The turnback is to accommodate trains up to 6 car x 26 m vehicles (DMU and EMU); with trains being able to access the turnback to and from Platforms 3-6 at Manchester Victoria station. As part of the MNTP programme, it was identified that the provision of a turnback facility to the East of Manchester Victoria Train station would provide operational flexibility. Currently, the platforms at Manchester Victoria must accommodate terminating trains, this restricts the availability of the through platforms, impacting performance and causing a timetable constraint. In a standard hour, two services, typically from Kirkby / Preston / Wigan are booked to terminate in the through platforms before the driver changes ends and the train departs in the opposite direction. Typical turnaround times are between 5-10 minutes, meaning that the platform, and route through it, remains occupied for the duration of the turnaround. The operational flexibility of the station would be improved if services could utilise a turnback facility to the East of the station. The turnback would also be a service recovery measure during perturbation. ES2-4 design and development was undertaken by WSP Limited and accepted by Network Rail. However, there are many instances within the designs where assumptions have been made stating that the TRU works would be complete prior to commencement of the project and all as built designs and source records would be available. OLE Infrastructure Scope of Work: The supply, installation, testing, and commissioning of new OLE infrastructure on the UP/Down Rochdale Fast and the new Turnback between Dalton Street and Miles Platting Junction (a combination of STC, TTC, and portals). New wiring on the UP/ Down Rochdale Fast and a new Turnback between Manchester Victoria and Miles Platting Junction. All associated OLE works to support the new infrastructure. This includes all hand back deliverables, such as redline drawings, O&M manuals, and attendance at AMP016 walkouts.
