Network Rail’s Design Services Framework

VolkerRail will deliver design services on Network Rail’s Design Services Framework (DSF), across the following single-discipline contracts:

  • Signalling: North West and Scotland (North West and Central and Scotland’s Railway)
  • Signalling: North East (Eastern)
  • Electrification and Plant – Plant: North East (Eastern)

Through the DSF, Network Rail will have access to VolkerRail’s design support network, closer supplier engagement, improved assurances and access to our industry experts.

Our design capability is a system-led approach, creating a strong performance output and a place for innovation to thrive. The skills range of our internal design teams, supported by the wider supply chain, covers every aspect of signalling, and electrification and plant design, which can be delivered either individually or as part of a fully integrated project. 

Our flexible approach is demonstrated by the scope and complexities of the projects we undertake, which range from small contracts to joint ventures and alliance projects.


With experienced in-house design teams based in Birmingham, York, Doncaster and also India, we offer a wealth of experience, and extensive services to support the development of projects from robust, risk-based feasibility and option selection, through to the detailed design of new and amended signalling. Key skills include scheme plan development, amendment of legacy interlockings and lineside infrastructure, level crossing control systems, signaller control and indications systems and SSI data preparation

Electrification and plant

Similarly, our in-house design teams based in Doncaster offer extensive knowledge and experience in the development and design of electrification and plant systems. With capabilities that extend across high and low voltage transmission, traction power distribution, fixed plant, lighting and building services, we are capable of supporting schemes from small, one-off, single discipline maintenance projects, to large, multi-million pound, complete turn-key power distribution packages, with flexible and professional electrification solutions to meet every need.
