Now that is what you call a ghost train.

One of Japan's leading architects has designed a near-invisible - yes INVISIBLE - commuter train that is expected to debut in Tokyo in 2018. Commissioned by the Seibu Group in honour of the company's 100th anniversary, Kazuyo Sejima's marvel of design uses semi-reflective and semi-transparent materials to mirror its surroundings. The idea is that the train will blend into both countryside and city environments, while passengers relax in luxury carriages designed to 'feel like a living room'. Sejima and Ryue Nishizawa, who together founded SANAA, were named Pritzker Architecture Prize laureates in 2010 - the most prestigious honour in architecture. Some of the duo's other designs include the New Museum of Contemporary Art in New York and the Serpentine Pavilion in London.
