A fleet of leaf-removing trains will spray 32 million litres of water to remove fallen leaves from tracks across the North West during this autumn.
Rail bosses say leaves create a slippery coating when left on tracks, acting much like black ice on roads. If left untreated, it can make it almost impossible for trains to accelerate and brake properly.
Network Rail say their eight cleaner trains use high-pressure water jets to remove leaves. The fleet will cover more than 102,000 miles over the next 10 weeks.
