Perth & Haymarket Station Off Indicators
At Perth Station, LNER faced accessibility issues on Platform 7, where they dispatched northbound trains. The width of the platform and the step from the train cause delays when disabled passengers board or alight. Platform 4 was an alternative but lacked visibility of the down departure signal P165, preventing safe dispatch. Installing an “OFF” indicator on Platform 4 now allows LNER to move northbound operations there, improving safety and reducing delays.
At Haymarket Station, LNER faced visibility issues on Platforms 1 and 3 due to platform curvature and obstructions that hindered viewing the departure signals; EH512 and EH510. This forced train managers to walk long distances, adding to dwell time and causing delays. New “OFF” indicators on these platforms now improve visibility, reduce dwell times, and maintain timetable adherence.
DigiSig Rail were instructed by Works Delivery Scotland to undertake the Engineering Stages 4 & 5 Signalling Designs required to allow the installation and testing of the new “OFF” indicators at both Perth and Haymarket.
Our Role
As part of the Engineering Stage 4, DigiSig Rail carried out base plan surveys of the affected areas to confirm positions of relevant signal positions, produced signalling scheme plans for both Perth & Haymarket and preparing the necessary designs, documents and assessments to minimise design risks and assure all Signalling Engineering activity.
Following completion of the Engineering Stage 4 design and receipt of Approval in Principle (AIP) for the scheme, our team then undertook the Engineering Stage 5 works which consisted of Control Table design and associated wiring alterations required.

Steven Rudland/ Performance Hub Manager LNER
“More thanks are due for the help to get two new Off Indicators installed at Haymarket, Eastbound platforms 1 & 3. Due to cluttered station furniture as well as usually busy services, signal sighting is difficult for our Train Managers at the rear of the train, meaning they may have to move to gain sight -causing us safety and performance risks. They have now been removed somewhat after the recent installation. What makes me particularly proud about this, is the suggestion came from our Aberdeen-based Train Managers, as I was able to raise a business case on their behalf, and get this over the line to make their job easier. Scotrail and other TOCs should see a benefit too! Thanks go out to Graeme Robertson, Julie-Ann Kean, Kayleigh Waterfall, Bob Loch, Kirsten Dempster, William McGinlay, Russell Simpson, Don Roberts, Barry King, Samantha Reid, Graeme McKinnie, Warrick Dent, Paul Makepeace, Liam Sumpter, Alex Hynes and the late Guy Whaley who helped put me on the right path to get this delivered.”
Richard Mallinson/ Senior Manager Network Rail Signalling Schemes
“Good to get out with the team for the Commissioning of 2 x OFF Indicators at Haymarket. The commissioning of these assets added to last week’s commissioning at Perth has seen the successful completion of this scheme for the WD Scotland team. A positive result providing enhanced reliability and performance benefits at these key stations.”
