The calculation of air pollutants for electric HSR operations is the same
as for conventional rail operations,except the energy demands change.
For instance, an energy consumption value of 864 BTU/passenger-mile (567 kJ/pass-km) is reported for the Japanese Shinkansen for a 50% load factor (JNR 1984)
As before, roughly twice this energy requirement must be used at the electric power plant due to inefficiencies and line loss.
