London Transport

London Transport were the governmental agency that administered the London Underground. During the dinosaur invasion that was a part of Operation Golden Age, the Brigadier and the Third Doctor needed to blow a hole in a station on the Metropolitan and Circle lines. The Brig quipped to the Third Doctor that if the Doctor were wrong about the necessity of damaging the tube station, it would be difficult to explain to London Transport. The Doctor reassured his friend by saying, "If we don't get down there, there won't be a London Transport to explain to." (TV: Invasion of the Dinosaurs)
