A driverless shuttle service is taking its first passengers to and from the terminal at Luton airport.
Luton Direct Air-Rail Transit (Dart) was due to open in 2020 and has finally came into use.
The 1.4-mile (2.2km) track links Luton Airport Parkway railway station to the terminal with a journey that takes about three minutes.
Currently it is operating on a restricted timetable of four hours per day.
This is due to increase to a 24-hour service in around three weeks’ time. It will eventually replace the shuttle bus service.
The King was one of the first people to ride the cable-drawn shuttle, when he was given a special trip on December 6, during a visit where he also had an egg thrown towards him while he was in the town centre.
