STEERING CHARACTERISTICS OF BOGIES

This article, which is a description and analysis of the fundamental steering properties of four-wheel bogies, considers the limitations of bogie vehicles for high speed operation and compares their performance with estimates for the APT, the 250 Km/h advanced passenger train. Because bogies act to attenuate the effect of road bed irregularities, there are strong reasons to favor bogie vehicles whenever passenger comfort is a major consideration. A possible disadvantage is that bodies designed to be dynamically stable at high speeds may need a primary suspension which is too stiff for good steering properties. It is concluded from mathematical studies that a dynamically optimized bogie still provides satisfactory guidance, comparable with a four wheel vehicle with a very soft suspension, and bogies should not, therefore, be regarded as unsuitable for high speeds.
