Rail signalling project Highland Main Line Enhancement Project

Project Spotlight:

Aberdeen to Inverness, Highland Main Line Enhancement Project – Phase 2 Aviemore

Project Timescale: 19 weeks 

Project Team: 

Key deliverables:

  • Lift and shift mechanical operated points equipment at Aviemore
  • Lift and shift signalling location and mechanical signal wire and associated signalling cables at Pitlochry

Project Review:

The Aviemore programme was completed on time and against schedule – to accommodate the track work renewal stages of the project. Associated works at Pitlochry facilitated all ground work to accommodate a platform extension. The proven signalling maintenance testing methodology undertaken by the NRL team, ensured no new testing specifications needed to be developed – delivering a financial saving to the project. 

Please pass on my thanks to the team working on this project. Despite a few concerns my end before commencing the project, there was no need to be worried – the team have done a sterling job, including the set-up prior to undertaking the work.

Rail project Greenhill to Dundee Line

Project Spotlight:

Millston Burn Bridge Renewal, Greenhill to Dundee Line, Scotland

Project Timescale: 1 year 

Project Team: 

Key Deliverables: 

  • Survey Report 
  • Cable slew S&T disconnections and reconnection 
  • SMTH Testing 

Project Review: 

A comprehensive programme was delivered to carefully manage the disconnection and reconnection on two lines, controlled by the local signal box at Greenloaning. Cable routes were in both cesses across the bridge, with a combination of buried cables, cables on hangers and cable contained trough route. In addition, mechanical signalling wire, stay wires, mechanical pulley wheels, signal post telephone, track circuit and TPWS needed to be carefully managed. 

To ensure safety, disconnections and cable protection was put in place – which included temporary cable support for the calculated cable weight, for the length of the track removal and excavation. All signal wires and TC cables required labelling before disconnection, before being reconnected by SMTH qualified staff.
