This article explains the need to improve the aerodynamic performance and energy efficiency of high speed trains. It attributes the need to rising energy prices and the need to reduce carbon dioxide emissions. It identifies the factors cover by the aerodynamic requirements for the safe operation of high speed trains set out in the High Speed Technical Specification for Interoperability in Europe, which include safety against crosswinds, pressure loads in the open air and in tunnels and reducing the problem of micropressure waves.
