Station platform upgraded with 48 precast slabs

CPR Rail Division have completed a project to upgrade the platform at Georgemas Station, on behalf of Network Rail. The works included the renewal of the existing reinforced concrete slabs that form the station platform with new slabs, and also to install dual cope tactile slabs. The operational length of the platform is 118m.

The works involved removal of the existing concrete slabs that span between the concrete portal frames and then installation of new structural slabs with dual cope tactile units on top of them to achieve required gauge clearance for new class 153 rolling stock trains.

A total of 48 precast concrete slabs (4.5m x 1.8m) were manufactured and supplied by CPR Precast Concrete Products Ltd. In addition, the existing platform ramp had to be removed and replaced with new staircase access.

The works can be summarised as,

  • Site prelims including temporary hard standing, site protection, accommodation, and security
  • Removal of works including copes, excavation of surfaces, concrete slabs and waiting shelter
  • Installation of works including, 48 concrete precast slabs including waterproofing, surfacing and line painting
  • Ancillary works including dish channel, kerbing, shelter including foundations, collapsible and concrete bollards, stairs, gates, and handrail.

The main challenges with this project were the removal and replacement of 48 new slabs within 12 shifts. The products were produced at CPR’s Precast Concrete plant, where they were cube tested prior to being transported to Georgemas station.

All works were completed during nightshift with possession after normal operating hours. The station is in a remote location, being only 16km from Thurso, and the CPR team successfully co-ordinated the deployment of the cranes, concrete slabs, and operatives to ensure there was no disruption to passenger services. Only 12 shifts onsite were required to complete the works due to CPR’s significant experience working within the rail environment.
