2 2 Large Cross‐Section


2.2 Large Cross‐SectionThe carbody has a larger cross‐section than the world’s other high‐speed rail system

Shinkansen Type Width (m)

TGV‐Atlantique 2.904

ICE‐3 2.95

Shinkansen (Series E2 etc.) 3.38

Permit a layout of five seats ( 2 + 3 ) per row

Shinkansen can provide the spacious and comfortable space for passengerp p g

2.4 Air‐tight Structure

Pressure variation• Air‐tight car body structure

Pressure variation in air‐tight passenger room

Pressure variation at outside of car in tunnel

Withoutair‐tight

Uncomfortable shock

• Air‐tight apparatus for car body openings

• Special ventilating apparatus

Air‐tight Method of Carbody Air‐tight apparatusfor car body openings

• Use of Continuous welding at basic structure • Use of forced sealing apparatus

Forced Door Locking MechanismEvaluation of Strength against Pressure Load

2 5 Aerodynamic Shape


2.5 Aerodynamic ShapeNose shape is important factor for high speed operation and for environmental condition

• Minimize air resistance• Minimize pressure change when the train runs into a tunnel• Minimize rolling when the train runs with the nose at the rear end

Long nose to minimize pressure change

Aerodynamic Shape Computer Simulation(Tunnel Passing Simulation)

Smooth and flush surface to minimize aerodynamicpressure change to minimize aerodynamic resistance



Computer analysis of the front nose shape to minimize wind resistance

and air pressure

Bogie side cover and Side under floor cover to minimize aerodynamic resistance

Bottom under floor cover to minimize aerodynamic resistance
