Our history

Since 1999, Sentinel has been the chosen identity card scheme for making sure that people who work on or near Network Rail’s infrastructure have basic competence and are medically fit to do so. The system, owned and developed by Network Rail,  is  based on a central database and a common system for checking that people hold Personal Track Safety (PTS) or Industry Common Induction (ICI), other critical competences and medical fitness to work and in-date Drugs and Alcohol certificates, all assured against a ‘single version of the truth’.  Originally a paper-based approach was taken and the system – though better – was not perfect.  Re-printing of cards was necessary if something changed and there was no capability to easily verify or ‘authenticate’ the information being presented.  Even with the introduction of a telephone hotline the data indicated that full checks were rarely carried out.

2013 saw a significant upgrade to the Sentinel system, making use of electronic chip technology within newly formatted cards.  This allows near ‘real time’ checking of competence using a variety of authentication methods such as smartphones, PC access or simple scanning of a QR code on the new cards.  The software has been designed and developed by an external provider, Reference Point Limited (RPL), subcontracted from MITIE security.  It is now possible to check the card against the central database in near real time using 3 and 4g connectivity.  In 2014, Transport for London became the first other Rail Entity to adopt the system and future expansion is under discussion with HS2 and the Highways Agency.

With further enhancement projects in 2016, the Sentinel system is now being used to control site access and improve the management of risk due to fatigue.  Until very recently, the prescribed route to becoming a Sentinel Card holder, in terms of competence, was to hold Personal Track Safety (PTS) as a minimum.  An initiative has also been made to bring Non Trackside employees onto the Sentinel Scheme using an Industry Common Induction (ICI) standard as an alternative prerequisite for inclusion.

Sentinel is introduced to the rail industry. A single database with printed cards used to verify rail workers competence and authority to work trackside.

Printed cards are withdrawn. Smartcard and web-based technology is introduced, enabling near real time assurance of authority work against a central database.

TfL adopted the Sentinel scheme. Watch a video with Joe Hickey (Transport for London) who played an integral part in the roll-out of Sentinel when it was adopted by London Underground. Joe explain more about the partnership.

Site Access is introduced enabling the management of work and travel time enabling the first steps in industry-wide fatigue risk management.
