Aerodynamic Forces on Freight Trains. Volume II. Full-Scale Aerodynamic Validation Tests of Trailer-on-a-Flat Car (Series II).

Aerodynamic forces were measured on full-scale Trailer-on-a-Flat Car (TOFC) configurations and a reliable data base was established for validation of wind tunnel test programs. The drag, side and lift forces were determined on two trailers mounted on an instrumented flat car, each by means of a...

Standby Power for Railroad-Highway Grade Crossing Warning Systems

The requirements for standby power at railroad-highway grade crossings, as established by the states, the Association of American Railroads, and the individual railroads, are described. Standard means of satisfying these requirements, using 115 vac primary power and storage batteries for standby,...
