Network Rail awards £49 million Shotts Line electrification contract to Carillion JV
Carillion Powerlines Ltd has won the contract to deliver the electrification of the Shotts line between Holytown Junction and Midcalder Junction.
The contract covers the physical delivery of all elements required to electrify the line, such as erecting stanchions and stringing the overhead powerlines, and will be carried out in tandem with work being delivered on a range of bridges as part of a route clearance programme to ensure the power cables can run under structures on the line.
New electric trains will be introduced on services between Edinburgh and Glasgow Central via Shotts following completion of the work using the new Hitachi class 385 rolling stock and will offer improved reliability and increased capacity for passengers.
Transport Minister Humza Yousaf said: “The Scottish Government’s funding of the electrification of the Shotts Line, and our overall £5 billion package of investment in our railway, demonstrates our ongoing commitment to the Scottish rail network.
“This work contributes to the transformation of services across the central belt as part of the wider package of investment to enhance rail travel between the country’s two biggest cities, meaning passengers will see shorter journey times, increased capacity and better reliability.
“This contract award is a major step forward in the delivery of the electrification programme and rail passengers across North Lanarkshire and West Lothian will feel the benefits for many years to come with an improved service on the line.”
Iain McFarlane, Head of Programme Management for Network Rail, said: “This contract is a significant milestone for the delivery of the Shotts electrification project and further underlines our commitment to investing in and enhancing our infrastructure as part of our UK wide railway upgrade plan.
“Throughout this project, we will work closely with contractors, train operators and other stakeholders to deliver in the most efficient and cost-effective way possible while minimising disruption for both lineside communities and passengers.”
Martin C. Smith, Managing Director, Carillon Powerlines said: “We are delighted to have been awarded this contract to electrify the Shotts line across central Scotland and we look forward to working with the project team to enhance the railway network.
“This award reflects the depth of experience we can demonstrate in delivering infrastructure enhancements in a railway environment and will further enhance the relationship we have developed with Network Rail. We look forward to working with the project team.”

China’s Broad Group builds 10-storey apartment in 28 hours
The China-based manufacturing enterprise Broad Group has managed to construct a 10-storey steel apartment building in just over a day. Constructed in the city of Changsha in China, the company used bolt-together modular units known as its “Living Building System”.

Broad Group, a manufacturing company based in Changsha, constructs a range of air-conditioning, heating, and prefabricated structural units. It accomplished the challenge in 28 hours and 45 minutes, enlisting help from three cranes and an on-site workforce.
Broad Group’s “Living Building” system
Designed to be easy to transport and install, Broad Group’s “Living Building” system uses components that are able to fit into a standard shipping container, and then be bolted together when they reach the site. Ductwork and wiring are fitted directly by the factory, the company said.
As part of the system, Broad Group’s B-Core steel slabs are used as structural elements which, the company claims are 10-times lighter and 100-times stronger than conventional slabs. The company also says they have the ability to resist earthquakes and typhoons, and that it costs less than a carbon steel building and has low energy consumption.
Broad Group also says that buildings of up to 200 storeys, supertall towers, could be built using the same modules due to the B-Core steel slabs’ strength and lightness.
Other Broad Group projects
Broad Group has completed other significant projects in the past. In 2012, for instance, it attempted to build the tallest tower in the world in Changsha at 838m, which would have made it 10m taller than the Burj Khalifa in Dubai. The company claimed it could have made the building, named Sky City, in just eight months. However, due to not receiving approval, it was never built.
In 2015, the company accomplished another “speed-build” challenge, constructing a 57-story tower using the “Living Building system”. It was completed in just 19 days.
