Great Western main line
- Automatic Supply Restoration system
Westermo Ethernet switches signal fewer delays and disruption for Great Western main line
With increasing passenger numbers and the threat of fines for not meeting punctuality targets, British rail companies are coming under increasing pressure to minimise the impact of infrastructure faults. However, a sudden loss of signalling power caused by cable or equipment faults, theft or vandalism can cause significant delays and disruption to a busy network. It is therefore essential to put in place suitable systems that not only identify failure points, but also return the rail network back to full operation as soon as possible.
One way to overcome these problems is to install an automatic supply restoration system. These will detect a loss of power, inform operators and maintenance teams and quickly restore power to signalling equipment. This reduces delays, outages and minimises impact on customers. Installed at the trackside, an automatic supply restoration system isolates a circuit fault and then restores power automatically by reconfiguring the supply from the principal supply points, reducing a power interruption to less than thirty seconds.
One such system, supplied by Schneider Electric, is being installed as part of a major project to upgrade to the signalling on the Great Western main line between Newbury and Reading in Berkshire, UK, a distance of about 17 miles. Westermo’s Lynx 110-F2 Managed Ethernet Switch meets these challenging requirements and over 60 units are being installed as part of this upgrade project.
