Train Aerodynamics

Appendix 2

Data for aerodynamic crosswind force coefficients

The tables that follow list the available data for crosswind force coefficients for the four categories of train used throughout the book – high-speed passenger, medium-speed passenger, low-speed passenger and freight. They are presented initially by the nature of the track geometry – flat ground (FG) with or without a track simulation first (Single Track Ballasted Rail (STBR) or Double Track Ballasted Rail (DTBR)) and other ground simulations next, such as viaducts or bridges. They are then categorised as being either low-turbulence simulations (LT) or atmospheric boundary layer simulations (ABL). The individual results are then tabulated by reference and date (Tables A2.1–A2.4). Full ...
