Network Rail work hard to predict and plan for any potential problems caused by snow and ice on the rail network, and have a number of ways to address them quickly.
With snow and ice forecast in parts of Britain this week, here’s a look at how Network Rail help to keep the railway running when temperatures dip below freezing.
Typical preparation for winter weather includes making sure the track is clear, with no overhanging snow-covered vegetation, no icicles at tunnel entrances, and spare parts delivered where needed for assets sensitive to snow and ice. Fences on major routes prevent snow blowing onto the tracks.
Network Rail’s Orange army patrol the tracks day and night to clear snow and ice from junctions and tunnels, while a helicopter fitted with thermal imaging identifies points heaters that aren’t working effectively.
Heaters are attached to points to prevent ice forming, and there are protective covers on 4,000 points and 2,500 points motors to keep out snow.
Network Rail weather experts discuss with route teams the actions to take. This might include:
Network Rail’s dedicated fleet of machines, from snow ploughs to specially developed Snow and Ice Treatment Trains, are ready at depots across Britain and can be deployed where needed when ice and snow are forecast.
