Rail signalling design defines how trains are safely detected and controlled across the network. An overview of the discipline and how OSL supports signalling projects through design, testing and commissioning.

Winter brings additional safety challenges across the railway. A practical look at rail and vehicle safety considerations during the festive period, as the network continues to operate around the clock.

Electrification systems operate as part of a wider railway ecosystem. They interface continuously with signalling systems, depot operations, passenger facilities and monitoring platforms.

Functionally Equivalent (FE) Design is a structured approach used within rail signalling renewals where life-expired assets require replacement without altering the operational principles of the railway.

This week marked a meaningful moment of local history for OSL, as a blue plaque was unveiled to commemorate Ada Nield Chew.

Supporting City & Guilds Training and Intertrain at the Purley Training Centre. Practical, on-site engineering support that helps keep training environments accurate and fit for purpose. 

Reaching the 60% IDC milestone for the Beckton Depot Southern Expansion Concept Design. A collaborative, multidisciplinary approach.

OSL Global supported the delivery of the TPH project on the Windrush Line through a targeted SSI data change. Working alongside industry partners, the team safely recommissioned the interlocking and verified integration with critical operational systems.

The Isle of Wight Island Line Upgrade formed part of a programme to modernise the existing network ahead of the introduction of Class 484 rolling stock, requiring significant infrastructure works across multiple engineering systems.
