Although based at Waterloo, the drone is flown remotely by British company SkyBound from a control centre in Woolston, near Southampton, around 80 miles away. When an incident occurs, operators can launch it from a trackside docking station to provide live aerial footage to railway controllers, security teams and engineers. It could also shorten the time that power to the third-rail network has to be switched off, allowing trains to resume running sooner. Trespass remains one of the biggest causes of disruption on the South Western network. A trespass incident near Clapham Junction in September last year caused more than 57 hours of delays before the offender was jailed for eight weeks.
