The first public run of the Japanese ‘bullet train’, the Shinkansen, on the 1st of October 1964, captured public imagination worldwide. And it wasn’t just the train’s sleek look or its high speed that made the headlines. Behind the train’s futuristic exterior lay a whole host of engineering innovations: new pantographs, automatic signalling, revolutionary drive units. Since then, very fast train travel has become available in over a dozen other countries. Places such as China and Spain have overtaken Japan when it comes to top train speed or the extent of the high-speed network. But the recent rise in remote working has reduced the demand for business rail travel and commuting. So what does the future hold for high-speed rail?Iszi Lawrence talks about the origins of high-speed rail and its current state to historian of modern Japan, Prof. Jessamyn Abel from Penn State university, civil engineering professor Amparo Moyano from the University of Castilla-La Mancha, Consultant Editor of the Railway Gazette Murray Hughes, poet Jan Ducheyne and World Service listeners.(Photo: A Shinkansen train arrives at a Tokyo station.
