You probably noticed that London Underground celebrated its 150th anniversary last year. At the same time, the Heathrow Express quietly enjoyed its 15th birthday. As a geeky kind of spin-off from our Secrets of the Tube series, we recently took a ride in the cab of a Heathrow Express train, from Paddington to the airport.
As the video shows, the line turns out to be more interesting than you might imagine. We were shown unused platforms and cavernous spaces. And we also discovered that one of the capital's shortest rail links — the shuttle between Terminals 1,2,3 and Terminal 4 — has as many drivers as it has stations.
