Osborne has secured a £7M Crossrail signalling enabling works project.
The contractor will deliver signalling renewal on the 27km “west outer” route from West Drayton to Maidenhead.
Works will involve design and construction of infrastructure including concrete bases; renewal of concrete cable troughs; site clearance; fencing, guardrails and safety barriers.
The project, for Network Rail, will be completed by spring 2013.
Osborne executive director Dave Hooper said: “We will be using high street environment working best practice and innovative construction techniques to deliver these works as efficiently as possible while remaining focused on the safety and operation of the railway.”
Network Rail Crossrail programme director Jorge Mendonca said: “My team’s role is to transform the surface railway to make Crossrail a success. The work Osborne is doing is an important piece of this complex jigsaw.”
