Developed by Central Japan Railway Company (JR Tokai), the trains focus on passenger safety and comfort, and are equipped with constant speed control systems, vibration detection systems and new braking systems. The new innovative systems contribute to the overall safety of operations.
Similar to the previous N700 fleet, the new N700A trains offer a number of technical improvements over their predecessors, including LED lighting (which is around 20% more efficient than the lighting system in the N700), bogie vibration detection, enhanced ATC, and improved brake discs which reduce braking distances by up to 10%. Sound absorption panels, used in some of the N700 fleet, are now used throughout the N700A, which seats 1323 passengers.
The N700A adopts the tilting system introduced on the N700, which allows operation at up to 285km/h on the Tokaido Shinkansen and 300km/h on the Sanyo Shinkansen.
The trains also feature a new cruise control system, known as the fixed speed running device, which receives data on gradient and curvature from trackside transmitters installed along the Tokaido Shinkansen, allowing the train to automatically adjust power output according to the specific infrastructure of the route.
The first N700As entered service in February 2013, replacing series 700s on Tokyo – Osaka services, with energy consumption reduced by 19% on the N700A than on the series 700.
