Heart of Wessex line upgrades

We’re making major improvements along the Heart of Wessex line from Castle Cary to Weymouth.  

Since February 2020, we’ve been renewing key stretches of track, replacing bridges and carrying out essential maintenance at our stations. 


Our work over the last three years has been a serious investment to improve the reliability of the Heart of Wessex line. 

Improving the railway infrastructure, through renewing track and repairing bridges will mean less delays and smoother journeys for our passengers. 

Taking advantage of the line closure we’ve made improvements to the stations along the route, installing tactile pavings for better accessibility, resurfacing platforms, cleaning and painting to make the railway more welcoming. 

Teams have also cleared overgrown vegetation along the route which have helped prevent lengthy, emergency railway repair work. 

Our Projects

This ongoing improvement project started in February 2020 when we replaced a bridge at Yetminster, then in March 2021, we carried out essential maintenance at Yeovil Pen Mill station. 

In November and December 2021, we replaced four miles of track between Maiden Newton and Yetminster, improved Weymouth and Upwey stations and carried out bridge and track maintenance. 

In September 2022 a week-long closure from Weymouth to Yeovil Pen Mill saw our engineers replace 1950s track in the Yetminster area, overhaul the Yeovil Pen Mill signal box and resurface the platform at Yetminster station. 

The latest closure in February and March 2023 saw our teams successfully complete two back-to-back 5-day weekday closures between Castle Cary/Yeovil Pen Mill and Weymouth. 

Our engineers took advantage of this extended line closure to complete multiple improvement works along the line. During 240 site hours, we: 

  • Renewed over 2,000 yards of railway through Thornford station, replacing track and old timber sleepers with new concrete ones. 
  • Refurbished Maiden Newton station, repairing the canopies, giving the station a clean and a fresh lick of paint. 
  • Installed new tactile pavings at Yeovil Pen Mill station to keep all our passengers safe 
  • Cleared overgrown vegetation and maintained key bits of railway infrastructure. 

From Monday 16 to Friday 20 October 2023 our teams worked round the clock to replace 758 metres of 1950s track between Maiden Newton and Chetnole, bringing yet another part of this line up to modern standards.
