1. Features of Tokaido Shinkansen Tokyo Shin-Osaka Distance: 515.3 km Stations: 17 Max speed: 270 km/h Nagoya TOKAIDO Shinkansen Line Safety : No deaths due to train accidents Stability : Average delay time 0.5 min/train (ave. over past 10 years) Comfort : Comfortable & quiet ride Convenience :High speed/frequency/capacity 291 trains/day (2004) 135 million passengers/year (2004)

2. Changes in Train Schedule 291 trains/day 60 trains/day Trends in number of trains 295 60 1964 (start of operation) 2004 (present) Features of Tokaido Shinkansen ’ ６４ ’ ７０ ’ ７５ ’ ８０ ’ ８５ ’ ９０ ’ ９５ ’ ００ ’ ０５ Nozomi Hikari Kodama (Trains) Requires high level of operation management

3. Benefits of new ATC and brake-control mechanism New ATC Current ATC Braking start point 1. Shorter operating interval/time 2. Improved riding comfort 3. Improved system reliability Free run distance Brakes (med) command Brakes (med) output Brakes (Hi) output Brakes (Low) output Operating patterns (Normal brake scanning speed) Brakes Following zone Safety brakes (Scanning speed of emergency brakes) Station Introduction of New ATC Goal: improve transportation capacities, comfort, and schedule flexibility Reduce constant- speed section Reduce low-speed section (entering station) Improved riding comfort through smooth breaking
