Bio

I am a hard working, conscientious railway signalling engineer who has been involved in the industry for over 20 years. Starting near the bottom as a Fast Track Trainee for Jarvis Rail, TUPE'd to Network Rail in 2004, working my way to being a Senior Project Engineer, responsible for a six-person engineering team delivering signalling and multi-disciplinary railway projects across the Network Rail Infrastructure from Penzance to Invernsess. In my role I also provide mentorship and support to both my immediate team as well as the wider department and always make the effort to make myself available for anyone to contact at any time. As a Senior Project Engineer I provide the engineering lead on small and medium sized projects ranging up to £12 million in value, but frequently the more important projects that are there to improve safety and performance, such as providing "flashing aspects" at Potters Bar, Huntingdon, Peterborough, Harpenden, Radlett, Batley, Heaton Lodge and Mirfield East for faster junction transitions, replacement of obsolete equipment, including electro-mechanical banner repeater signals, removal of "heavy pulls" at mechanical signal boxes through the motorisation of distant signals and points, SPAD (Signal Passed at Danger) mitigation works on multi-SPAD signals, or addressing overspeed incidents, such as the one that took place at Fletton Junction, south of Peterborough, where an Virgin Trains East Coast train passed over a set of points designed for 25mph at 56mph, resulting in injuries to passengers, although thankfully not a derailment. I have also participated in trials for new equipment, such as a Westica W2000 radio system for transmission of images from a "tail light camera" back to a signal box, replacing what would normally have been a fibre optic connection, and arguably more importantly the trial of the MCB-OD system, starting out with only a RADAR system but as the deficiencies with the RADAR were raised, the addition of LIDARs to the level crossing. Following the roll-out of MCB-ODs on the Ely-Norwich line issues were found with the "Fen blow" causing mud to obscure the LIDARs, so my team mobilised once again to fit new housings to the LIDARs which included electronic shutters, which would normally be closed to keep the lenses clean, but would open to allow the LIDARs to scan the crossing once a train has struck in. Since moving to Siemens in January 2023 I have been appointed as Contractor's Engineering Manager for Siemens on the Middlesbrough Capacity Improvement, York Area Performance and Capacity Improvement and Darlington Station Improvement projects, ensuring that Siemens deliverables are correctly integrated both internally within Siemens and externally with the other contractors appointed on these projects, ensuring that Siemens deliverables are compliant to both the contracts and standards and ultimately endorsing designs as Approved for Construction. It is anticipated that I will be involved in the trial of "WTS Trackside Interface" on the York Area Performance and Capacity project, due to a prohibition on copper cables, such as the existing datalink cables, being run into the York Rail Operating Centre equipment room.
