Across eight days, teams will strengthen structures, renew bridge decks and repair supporting steelwork across the route to boost reliability.

The work will involve essential repairs and renewals across key locations, including:

• Fixing and replacing parts of the walls that support the railway in Greenock, including new concrete sections.
• Replacing the main deck of the River Gryffe Bridge, repairing the steel to strengthen it.
• Repairing the steel that supports the railway on Houston Road, Georgetown.
• Fixing the steel under the bridge and replacing part of the platform with modern, durable materials at Station Road in Langbank.

To allow the project to be delivered safely and efficiently, the line will be closed from Saturday 7 to Tuesday 10 February and from Saturday 14 to Tuesday 17 February.

Bus replacement services will be available between Paisley Gilmour Street and Wemyss / Gourock.

Ross Moran, route director at Network Rail Scotland, said: “Delivering a safe, reliable railway for the communities we serve is always our priority.

“The work beginning this week on the Inverclyde line is vital to strengthening the resilience of the route. These improvements will help ensure passengers can continue to depend on this line for many years to come.

“By bringing several essential projects together into a single planned closure, we’re minimising the overall disruption and avoiding the need for repeated downtime further down the line.

“I want to thank passengers and local residents for their understanding and patience while our teams carry out these important upgrades.”

Mark Ilderton, ScotRail service delivery director, said: “While Network Rail carries out these vital improvements on the Inverclyde line, our focus is on keeping customers moving as smoothly and reliably as possible.

“We have a rail replacement plan in place to help people continue to travel with confidence, and we’d encourage customers to plan ahead and check their journey using the ScotRail website or app.

“This work represents an important investment in the future of the route, and we appreciate our customers’ patience and understanding while they’re delivered.”

While this is being delivered, Network Rail teams will also continue their vegetation management work as part of a £2.5m investment that has been ongoing since July 2025.

Delivered by QTS, the work involves cutting back and managing trees and plants that could affect the railway.
