PROGRAMME DESCRIPTION:

As part of Network Rail Sussex and Kent Region requirements to rectify non-compliances to 70no. Location Cases, Powersys was commissioned by McNicholas to provide upgraded Network drawings related to the 4 ELR routes, namely, RDG1, RDG2, AAV and PAA1. Powersys were also commissioned to carry out design works associated with increase in safety functionality and upgrade of on-track operational plant. The work entailed a mixture of survey works, preliminary and detailed ETE Design across track, civil and electrical disciplines

PROJECT DESCRIPTION (Survey Works):

The ‘Waterloo to Reading Power Supply Enhancement’ Project is a Network Rail CP5 Programme of Works aimed to increase the capacity within the Wessex route. This includes lengthening of platforms to enable 10-car train services to operate on the Reading and Camberley lines. As part of the scheme, Network Rail has commissioned McNicholas to undertake the ETE enhancements along the following routes in Wessex: AAV – Ascot Station to Ashvale Junction; PAA1 – Ashvale Junction to Farnham Substation ; RDG1 - Virginia Water Substation to Wokingham Junction; RDG2 -Wokingham Junction to Reading Station

McNicholas commissioned Powersys to undertake the ETE design for these works.

Survey Works for the Upgrade Design Works:

Initially, Powersys were instructed to update the site records for the 4 routes ahead of any detail design associated with upgrade works. This was a time intensive package of works and was dependant on possessions available from Network Rail. Due to the nature of works, a large degree of the work took place at night time possessions and thus, time on site was also limited. For this, coordination was key in making sure all information was collected in an efficient manner. Multiple teams of two were employed with the paper copies of the routes, with coordination meetings taking place prior to the day on site and a pre-on-site meeting up to two hours before start of possessions to ensue all information would be collected correctly.

This information was electronically captured immediately to ensure availability and ease of access during drawing update. Associated CAD drawings were requested and received from NR and all updates were made.

This was signed off and the next stage of the works began, namely capturing data for upgrade works design. For this, civil, electrical and track engineers went to site to capture plant location, wiring and track specifics.

With this information and updated records, design could then begin on detailed design of all upgrade and safety works associated with ETE works for the 4 sites. As part of this package, Powersys delivered 11 Substation and TPH site layout upgrade designs, over 60 TIS location packages, over 120 hookswitch replacement drawings and Con rail as well as rebated sleeper design packages across all 4 routes in the ELR area.

Stand-alone civil aspects of the works included the creation of multiple Form 002 & 003 packages for non-standard Tis development, a UTX and 4 URX designs also.

All works associated with the work and time intensive package was delivered on time and to budget and have now been issued for AFC.
