For the few weeks, passengers on Tokyo’s Yamanote line will be able to access an information service called Train Net through their smart phones via an on-board WiFi network. The service will provide train information — including the quietest and coolest cars — and location-based entertainment, dining, and shopping recommendations and coupons. WiFi access is limited to the Train Net service; customers will not be able to surf the web from the train. Japan Rail partnered with Mitsubishi for this project, which is currently installed on only one train for the month-long trial. Link to full story in Japan Trends.
