The investment will help to drive down delays and keep services running efficiently for passengers travelling through the station.

The work, which began on Friday 22 September and ended this week, included:

• Upgrading the track through the 127-year-old Dalmuir twin tunnels, which carry the railway underneath the Forth & Clyde Canal.
• Renewal of switches and crossings, pieces of rail which move to allow trains to switch from one line of track to another, to the east of Dalmuir station.
• Installation of new brackets to support the rails on Platform 5 at Dalmuir station.

A four-day closure of the line allowed engineers to combine three projects and deliver the work more efficiently, while limiting the time needed to close the railway to customers.

Kevin Haddow, project manager, Network Rail Scotland, said: “Our team has been working around the clock to deliver this project safely and efficiently. Their work will improve the long-term reliability of the line and we are pleased to have been completed the work on time and within budget.

“We would also like to thank passengers and residents for their patience during the project.”
