Drone technology will be deployed alongside seven specialist ‘leaf busting’ trains this autumn, to help keep passenger and freight services running on time.
Eighteen leaf-fall teams will work around the clock to remove fallen leaves – the railway’s equivalent of black ice on the roads, to help cut delays during this challenging period.
Leaves on the line can cause trains to lose their grip on the rails which means braking distances are increased. If this happens, it can cause trains to overshoot signals or platforms and affect signalling systems – making it harder for signallers to track where trains are. To combat this, specialist rail-head treatment trains (RHTTs) and multi-purpose vehicles (MPVs) will cover more miles than ever before, serving the newly opened Levenmouth Rail Link for the first time.
These trains use high-pressure water jets to clean the rails before coating them with a sandy gel that sticks to them, helping improve train wheels’ grip. Rapid response teams will trial the use of drones to inspect the rails for leaf contamination from above, without staff having to stop trains to access the track.
Between September 16 and December 6, more than 81,000 miles of track will be treated by this specialist fleet while teams of engineers will target leaf-fall black spots. The leaf-fall teams will also continue the use of ‘hydrophobic’ sand which sticks to the rails, giving trains more traction in slippery conditions. Network Rail will also equip ScotRail’s Class 334 fleet with the same sand, trialling its effect on several routes, including between Helensburgh Central and Edinburgh Waverley.
Ross Moran, route director at Network Rail Scotland, said: “It’s exciting to see our seven leaf-busting trains take to the rails in mid-September, part of our £7 million investment to improve performance by running more trains on time. To do this, we’ll be working as one team with colleagues across Scotland’s Railway to keep passengers and freight moving this autumn.
“Leaves on the line are dangerous, affecting trains like black ice affects road vehicles. To prepare for this, we’re using tried and tested techniques, as well as some innovative technology, such as drone inspections and hydrophobic sand, that will help break down leaves and improve traction for trains.”
