Alexander Dragunov is an architectural photographer, but his real passion is capturing images of trains. In this video, he gives a guided tour of his favourite metro system in Stockholm -- and reveals that it is indeed stunningly beautiful.
The St Petersburg-born photographer shot this video with the BBC to explain why he thinks Stockholm's is "the most beautiful metro in the world". He also talks a little about how he goes about capturing his images and explains that 10-minute waits between trains in the city makes it easy for him to capture the perfect photograph. [BBC]
