Bushey PSU: Achieving unprecedented schedule

Upgrading the West Coast Mainline’s (WCML) power supply at Bushey, Hertfordshire, has presented a long-standing challenge. Access to the line, where local commuter services run on slow lines alongside a busy section of the mainline, has been the principal challenge.

Testimonials

What our clients say about us

"As part of a value engineering exercise, Octavius proposed the opportunity to deliver an uncovered footbridge structure, to make the project more affordable in the face of increasing material costs and affordability challenges. Octavius and design partner Arcadis produced a proposal that was better value for money and saved on embodied carbon. These benefits helped Network Rail and the DfT make an informed decision on the derogation application and proceed with this solution betterment."
