There is a great Tube-themed video article on the BBC website today where they’ve followed the route of the Victoria line up on the streets, whilst mirroring the journey with a shot from the cab underground, and spoken/interviews with people along the way to reflect the wide diversity of people and languages along the route.
“The video below combines footage shot from a Victoria Line train, synchronised with its route above ground. The soundtrack echoes the most widely spoken language, after English, at each stage of the route. The underground journey takes just over 30 minutes, but we have condensed the footage into three minutes.”
