Network Rail has unveiled three new grinding trains costing £36m, which are now deployed across Great Britain to keep the track in good condition and provide passengers with a smooth, reliable journey.
The multi-million pound trains, which remove small layers of metal from the railhead, represent a significant investment for Network Rail Route Services, which worked with industry partners Loram and Colas Rail to design, build and maintain the new, improved models.
Network Rail’s new grinding trains are faster, more efficient and cheaper to run
The three trains have replaced a number of older grinding machines. The new models cost £1,000 less per shift to run, deliver 35 per cent more output, have increased reliability, better welfare facilities for the teams working on them and are expected to last for the next 30 years.
Improved grinding machines
This has been a fantastic example of different parts of the rail industry working together to deliver new and innovative solutions which ultimately improve the railway for passengers. By working together we have been able to deliver a safer, more cost-effective, productive machine which also provides a more comfortable working environment for our people to work in.

Route Services is here to provide the routes with the best services possible to help keep their railways running. The old machines were becoming unreliable and inefficient, so the investment in the new grinding trains was absolutely essential to keep the tracks in good condition to minimise the chance of defects and to keep passengers safely moving across the network.
I would like to thank both Loram and Colas Rail for the significant part they have played in helping us develop the new grinding trains. By working closely together we have been able to create an impressive new design using state-of-the-art technology and innovation, which will help maintain our railways for years to come.

Benefits of the new fleet
150-metre grinding train cost £12m and has a life of 30 years, which can be extended through timely maintenance
Increased metal removal due to more productive grinding at higher speeds, up to 15mph
Increased transit speed of up to 70mph to get around the network quicker, impacting fewer passenger and freight services
The machines are modular, therefore can be attached together to make a larger machine, or stay small to be more targeted
Modular design also means replacement of parts and components can happen much quicker, which in turn reduces the machine’s down time
Improved working within third-rail areas
The machines carry more water to dowse to prevent smouldering
Obstacle avoidance system to limit impact of trackside furniture and equipment
Full welfare facilities on board means a more comfortable working environment for the teams
