Colin graduated from Edinburgh University with an Honours degree in Computer Science. He has spent nearly 30 years in the industry working mainly on real-time systems, networking and security.  Colin is a well-respected Coder in the rail industry, and has worked for the world’s largest service providers to design networks for voice and data, including the first X.25/ATM/FR.


In previous years, he has led networking projects for SNCF, Bane Danmark, Deutsche Bahn the Rail Regulator in South Africa; air traffic controls system in UK, Romania and communications networks for Network Rail.  He sits on the UIC PETER group for Network Rail, which aims to harmonise communications for railways across Europe. Colin is now using his experience and knowledge to develop the next generation of DigitalRailway in the role of Principle Architect.


Tony Crabtree is a consultant with over 35 years in the rail industry. After operating trains & stations with BR he helped create the privatised railway structure and has since worked for train operators. He later joined ATOC to lead the ERTMS team with close involvement in the open source ERTMS initiative. He remains a founder member of the openETCS Foundation Board in Nuremberg

Lei Chen qualified with a BEng in Automation Engineering from Beijing Jiaotong University, and a PhD in Civil Engineering (Railway Traffic Management and Control) from The University of Birmingham. He is currently a lecturer in The University of Birmingham, and leading the Simulation Group at the Birmingham Centre for Railway Research and Education. He has been working in the area of railway traffic management and train control since 2004, involved in several large railway research and development projects in the UK and China, including the research and development of CBTC system, CTCS and next generation railway traffic management. His research interest mainly covers railway traffic management and train control, railway simulation and testing, railway safety critical system design. He also works extensively with the railway industry in Britain and China, as the Vice Director of Anhui Birmingham International Research Centre in Rail Transportation. He was awarded IMechE W. A. Agnew Meritorious/C. N. Goodall Award in 2010, and The Michael K. O’Rourke PhD Publications Award in 2012.

Clive is Professor of Railway Systems at the University of Birmingham and Director for Railway Research for the Birmingham Centre for Railway Research and Education.
Over the last 14 years he has developed a broad portfolio of research aimed at improving the performance of railway systems. He leads the University’s contribution in a number of large EPSRC, European Commission and industry funded projects. He works extensively with the railway industry in Britain and overseas. He currently leads a team of 11 research fellows and 16 PhD students.

Ten years’ experience in all areas of UK railway systems (both mainline and mass transit), principally in design, manufacture, installation, testing and commissioning as well as international experience in countries including Greece, Poland, Netherlands, Australia, New Zealand, Canada, India, Malaysia, UAE, Panama, Guinea, South Africa and Mozambique.
Principle area of interest is the development and deployment of modern complex Train Control Systems including (but not limited to) European Rail Traffic Management System (ERTMS), Positive Train Control (PTC) and Communication Based Train Control (CBTC), including Automatic Train Control (ATC) and Automatic Train Supervision (ATS).
Experienced with free-wired and solid state interlocking systems, ATC (Automatic Train Control) systems, control systems, communications systems (vital and non-vital) and rolling stock (both mainline and mass transit).
Lead Train Control Systems Engineer for the Simandou Rail Mine and Port Project, responsible for all aspects of development of signalling, train protection and control centre for new mine to port railway line in Guinea.
Technical Lead for the fitment of ETCS onboard equipment to all UK passenger rolling stock.
Was lead systems engineer responsible for the integration of control centre, signalling and ATC – utilising Invensys Distance to Go – Radio (DTG-R) system – on the Victoria Line Upgrade project for London Underground.

Sam Etchell started at London Underground as a graduate mechanical engineer in 2004, in 2006 Sam took up a position as a Testing and Commissioning Engineer for the Victoria Line Upgrade project.   Over the next 8 years Sam successfully led the Testing and Commissioning team through the delivery of 47 new 2009TS trains, a new Distance To Go Radio signalling system and a new Control Centre for the Victoria Line.  Sam then led an engineering team focussed on delivering further reliability improvements and a World Class Victoria Line train service for London Underground, this included the design, in house delivery and commissioning of the Remote Track Circuit system for the Victoria Line.  Sam is now a Senior Project Manager responsible for the delivering of the Testing and Commissioning on the CBTC upgrade across the District, Circle, Hammersmith and City and Metropolitan Lines.

Peter spent many years in road and air freight operations at Board level prior to bringing his experience and expertise to the rail industry in 2000.

Peter then gained experience in the rail industry and has operated in two heavy rail TOC’s as a Director between 2000 and 2005.

He was part of the team involved in the DfT’s remapping of the heavy rail network and has also worked on several rail franchise bids, winning three.

Peter worked with TfGM’s Metrolink team on a long-term interim basis from 2007 to 2012, overseeing existing day-to-day operations during the current £1.8 billion expansion programme.

Early in 2013 Peter became the Metrolink Director at TfGM, responsible for the expansion programme delivery and the on-going operation of the Metrolink network.

Peter is also a Director of UK Tram and Chair of the Promoter Group within UK Tram.

George Clark Bsc (Hons) FIRSE MIET

Engineering Director, Capital Programmes Directorate

London Underground


Responsible for the engineering across all disciplines within the Capital Programme of London Underground and the technical assurance as defined in the ROGS legislation, he has undertaken rail engineering roles in both the public and private sector during a career of over 30 years.

In his early years he designed, tested and commissioned central control systems for mass transit railways before leading the acceptance of modern processor-based signalling interlocking systems into the Tube and leading an international standards initiative to harmonise signalling interlockings and principles. More recently responsible for the Engineering and Delivery management of major Line Upgrades with modern Communication based Train Control Systems at their heart.

He has published many technical papers on the deployment of modern train control systems and the lessons to be learnt. Currently a member of the IET Railway Knowledge Network and an IRSE Council Member.
