Global High-Speed Rail Network Lengths (km)
Official UIC 2024 & China Railway 2025About the High-Speed Rail Physics & Network Model
Kinematics & Commercial Timetable: The simulator solves the equations of motion for electric multiple unit (EMU) trainsets:
t_accel = v_max / a and d_accel = 0.5 * a * (t_accel)².
A 350 km/h train requires approximately 176 seconds and 8.5 km to reach full operational speed at 0.55 m/s² traction acceleration, with symmetric braking curves and 3-minute interlock dwells per intermediate station.
Aviation Modal Shift & Carbon Parity: Rail trips under 4 hours capture 65%–85% of corridor passenger volume from airlines due to city-center terminal proximity. Emissions calculations assume 154 g CO₂/passenger-km for domestic commercial flights versus 18 g CO₂/passenger-km for modern high-speed electric trains powered by mixed national grids.
