PORR consortium to supply HS2 slab track

PORR's Slab Track Austria system has been chosen for HS2.

PORR’s Austrian Slab Track system has won the contract to provide the slab track for HS2 phases 1 and 2a – from London to Birmingham and Crewe, where HS2 will join the existing West Coast mainline.

The £260 million contract will see a partnership of PORR UK Ltd and Aggregate Industries UK design and manufacture the modular track system for the new line, except through tunnels and over some specialist structures.

Using a modular construction method, the concrete slab track will be manufactured offsite at a new purpose-built factory at Shepton Mallet in Somerset before being transported to site. Up to 500 new jobs will be created, mainly at the new factory.

The individual slabs will be manufactured at a new factory on Aggregate Industries’ site at Shepton Mallet, Somerset.

Once installed, the rails are then fitted onto the slab track. This type of system – which is used on several high speed railways across the world – will reduce maintenance costs and improve performance in comparison to traditional ballasted track.

David Poole, HS2.

David Poole, HS2’s procurement and commercial director, said: “HS2 is designed to provide reliable high frequency, high capacity rail services for millions of people across the UK.

“Slab track will provide long-term value for money with lower maintenance costs and greater reliability and that’s why I’m pleased that today we are awarding that contract to the PORR consortium.

“This award – and the announcement of the new factory at Somerset – is another example of how HS2 is already supporting companies across the UK, creating jobs and helping the economy recover from the coronavirus pandemic.”

PORR is one of Austria’s leading engineering companies and was one of the first companies in the world to develop a slab track system. PORR’s slab track system has been used to lay more than 780 kilometres of track worldwide, with its first stretch operating almost maintenance free since being laid in Langenlebern, Austria, in 1989.

Aggregate Industries UK is one of Britain’s leading providers of construction materials, employing more than 3,700 people at 300 sites across the UK. The new factory is planned to be built at an existing Aggregate Industries site in Somerset.

Simon Jukes, PORR UK.

Simon Jukes, managing director of PORR UK, said: “The PORR Consortium is delighted to have the opportunity to contribute to this major contract and will bring a wealth of technical expertise and experience in high speed rail and slab track to the HS2 project. We are looking forward to working collaboratively with the HS2 team to deliver a world class sustainable rail infrastructure for the United Kingdom.”

A separate Track Systems contractor – due to be appointed in 2022 – will have overall responsibility for managing and coordinating the design and installation of the complex rail systems in each section of the route. This includes the installation of the slab track manufactured by the PORR consortium and the interface with signalling and overhead power supply.

Separate specialist contractors will also deliver the rails, switches and crossings, high voltage power supply, communications and mechanical and electrical systems.
