Safety, sustainability and security polymer cable troughing

In the age of digital rail, with IP and radio-based communication and control systems, cable troughing can (on first glance) appear an uninteresting and low-tech subject. However, cable containment and protection is still an important part of the communication and control network. Over the last 10 years or so, the introduction of polymer-based cable troughing has contributed […]

Denmark’s rail infrastructure manager had envisaged a full rollout of ERTMS by the end of 2021 and CBTC by 2018. The ERTMS programme is now expected to go back by […]

Why I became a signalling apprentice

Pulling cable through the interconnected tunnels of London Overground’s East London Line while most people are asleep is a world apart from the predictable hours of most office jobs. As one of Carillion’s signalling and telecoms apprentices, Ben Dawson, puts it, ‘There’s a bit of graft involved.’ The East London Line reopened in 2010 following […]

Brexit – Signalling implications for the UK

With Britain on a course to leave the EU, how might the plans for signalling (control and communications) be affected? In short, nobody really knows, but a number of factors might now change the policy that had existed hitherto. Not having to comply with EU rules on interoperability, the non-inclusion of TEN routes and the advertising […]

ATACS – The Japanese Level 3?

The concept of ERTMS Level 3 has been around since the vision for a standardised European signalling system came about in the 1990s. Reducing the amount of track-based signalling equipment and doing everything by radio seemed an admirable goal but, despite early predictions and the emergence of something akin on lightly used lines, very little […]

Eurotunnel inaugurates GSM-R through Channel Tunnel

Eurotunnel has commissioned its track-to-train GSM-R network to replace the Channel Tunnel’s obsolete comms network. The €48 million project has taken six years to complete. GSM-R, a sub-system of ERTMS, is vital for the Channel Tunnel to fall in line with current European signalling and telecommunications standards. Nokia has led the end-to-end integration of the GSM-R […]
