Trusted to deliver Case study // Innovation through R&D The process of re-ballasting S&C using the ballast undercutting machines has reached its current efficiency limits and the speed of following the ballast undercutter using the current manual methods are limiting the output rates achieved. Network Rail recognise there are three main priority problems which require a solution to increase output and value. Namely, manual jacking and packing of the track following the ballast undercutter, the current process to replace the ballast is not quick enough, and the current method of on/off tracking the machine takes too long. Stobart Rail & Civils has developed a solution to all three problems in the form of individual machines, capable of working together as one – ‘the concept’. The con
