Railway of the Future

Samuel James Engineering recognises that its people are fundamental to its success.  Our complete range of products are designed and manufactured by a team of highly experienced engineers and support staff, who continually focus on delivering engineering-led technologies into today and tomorrow’s complex railway infrastructure projects across the UK.

Collaboration is a vital component of our ongoing engineering development, by taking this approach with both our customers and suppliers we can ensure that we remain at the forefront of technology developments and market demands. 

The team understands the need to push the engineering boundaries of its products, ensuring they have the necessary architecture to deliver digitally enabled signalling power management whilst supporting the objective of reducing the railways’ carbon footprint

Decarbonisation is an essential focus for all our product solutions to enable us to meet the needs of the railways of the future.
