Digisig Rail, NETWORK RAIL (SCOTLAND) LIMITED & London North Eastern Railway collaborate on Perth & Haymarket Signalling Project 👏

The Challenge 👀
At Perth Station, Platform 7 posed challenges for LNER’s northbound trains:
Accessibility Issues: Limited platform width and a significant train step caused delays for disabled passengers boarding or alighting.
Alternative Platform 4: It lacked visibility of the down departure signal P165, making safe dispatch impossible.
Solution: Installing an “OFF” indicator at Platform 4 enabled safer, faster operations, moving northbound services there and reducing delays.

At Haymarket Station, Platforms 1 and 3 faced visibility problems due to:
Platform Curvature & Obstructions: Departure signals EH512 and EH510 were hard to see.
Impact: Train managers walked long distances, increasing dwell times and delaying schedules.
Solution: New “OFF” indicators enhanced signal visibility, reduced dwell times, and improved timetable adherence.

The team at Digisig Rail were commissioned by Network Rail Works Delivery Scotland team to design and implement the following changes.
