Im Jamie, and i came into the railway in 2011 learning the job from the ground up and seeing first-hand how the railway really works.

I started my career as an apprentice track maintenance technician, completing a Level 3 Advanced Rail Apprenticeship and learning the fundamentals of Permanent Way such as: inspections, defects, possessions, and the responsibility that comes with working on a live, safety-critical system. That early exposure shaped how I think about the railway, not as diagrams or standards, but as assets, people, and decisions under pressure.

From there, I progressed through technical and supervisory roles, including time as a Technical Officer supporting inspections, patrols, and defect management, before moving into the Mobile Maintenance Train (MMT) environment. Working on the MMT meant 'operating at pace, planning and delivering work safely in tight access windows, managing rail defects, and responding to issues that don’t wait for convenient timing. It also meant learning how engineering decisions directly affect operations, and passengers in real time.

Over several years on the Sussex Route, I took on increasing responsibility, including acting as Section Manager for the MMT, leading teams, managing possessions, and making safety-critical decisions when things didn’t go to plan. Those roles demanded calm judgement, clear communication, and the ability to balance standards, risk, and operational reality skills that can’t be learned from paper alone.

I now work as a Section Manager (Track), responsible for over 120 miles of railway infrastructure across some of the busiest commuter routes in South London, Surrey, and Sussex, and leading a team of around 24 track engineers. My role covers everything from asset condition and defect management to real-time operational issues during degraded conditions, working closely with Route Control, signallers, MOMs, TOCs, and emergency responders.

Alongside the technical side, I place a strong emphasis on people and wellbeing. I’m a Mental Health First Aider, IOSH qualified, EngTech registered technician, and a member of the Permanent Way Institution, but more importantly, I care about how people are treated on the railway and how pressure, communication, and culture affect safety and performance.

Why this site exists

Over the years, I’ve seen rail infrastructure explained either in oversimplified soundbites or buried under layers of jargon that exclude most people including some who work on the railway itself.

Rail Infrastructure Explained exists to bridge that gap.

This site is about explaining:

• How track and infrastructure actually behave

• Why defects matter and when they really matter

• How engineering decisions feed into operational outcomes

• What “safety of the line” looks like in practice, not theory

• How pressure, time, and human factors shape real decisions

Everything here is informed by experience not opinion for the sake of it and shared with respect for the people who maintain, operate, and rely on the railway every day.

If you work on the railway, I want this to feel familiar and honest.

If you don’t, I want it to finally make sense.
