The framework for the boxy front of the bullet train and a smart passenger cabin were shown to media representatives.
The key feature is that the new N700S series will have only two types of cars--except for the head and tail cars--because underfloor equipment have been streamlined. By comparison, the current-generation N700A series has six variations.
JR Tokai hopes the fewer number of car variations will boost sales of the new Shinkansen to other railway operators in Japan and abroad because it allows for more flexible arrangements, such as an eight-car train and a 12-car train, instead of the current 16-car formation.
The new train will debut on the Tokaido Shinkansen Line linking Tokyo and Osaka in fiscal 2020, and the unveiling of the new bullet train took place at the manufacturer Nippon Sharyo Ltd.'s plant in Toyokawa.
The head car of the N700S bullet train is more angular than the N700A's. This lessens the horizontal oscillations the passengers feel by changing air flows.
The new train is also more eco-friendly, consuming 7 percent less electricity than the current model when it runs at 285 kph.
If an emergency automatic brake is applied in the event of a major earthquake, the N700S series halts after traveling another 2,800 meters, compared with the 3,000 meters required for the current model.
