Surebridge was set up by Simon and Helen Errington to provide consultancy services in the areas of rail systems and safety engineering, with a particular focus on ERTMS.
Simon has experience from working on the introduction of several new computer-based interlockings and VDU-based control systems to the UK railways, acting both for the supplier and as an independent safety assessor. More recently he was responsible for obtaining safety approval for the Cambrian ERTMS Level 2 scheme which was the first implementation of ERTMS by Network Rail.
The photo at the top of the page shows a Class 158 running in Level 2 as it leaves Dovey Junction on the way up the coast towards Pwllheli.
