The upgrades aim to improve the long-term resilience and reliability of the line and are scheduled to take place from Saturday 7 to Tuesday 10 February and from Saturday 14 to Tuesday 17 February.

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: “This work is part of our commitment to maintaining a railway that communities and visitors can continue to rely on.

“We’ve combined a number of essential projects into one single closure, avoiding the need for multiple periods of disruption over a longer timeframe.

“We’re grateful to passengers and local residents for their patience and understanding while we carry out these improvements.”

Mark Ilderton, ScotRail service delivery director, said: “ScotRail is focused on maintaining reliable travel for customers while Network Rail completes these important improvements in Inverclyde.

“Our rail replacement services are designed to keep people moving with confidence, and we would encourage customers to check their journey in advance on the ScotRail website or app.

“This investment will deliver long‑term benefits to the Inverclyde line, and we’re grateful for customers’ patience while the work takes place.”

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.
