For centuries , the gusts of air produced as Britain's trains rush around the country have been wasted – until now. In a UK first, rail company LNER have installed three experimental wind turbines alongside the track, to harness the turbulent airflow blasted out by passing high-speed trains and turn it into electricity. The turbines, named "Windiana Jones", "Sir Spins-a-lot", and "AC Breezy", have been installed alongside the East Coast Main Line at Hitachi Rail’s Craigentinny depot in Edinburgh by LNER and clean energy infrastructure firm Treeva. The six‑foot‑tall devices, made from "upcycled materials", are the first turbines to be operated next to a UK main line. They require no grid connection, and their design allows for easy deployment on hitherto unused railway land close to the tracks.
