The Private Builder's Contribution to the Development of Freight Stock

Abstract

Over the last few years, private builders have designed and built large fleets of wagons for private owners to operate on British Railways in transporting their products rapidly in bulk. This paper describes a number of these vehicles, discusses aspects of design and standardization, and reviews many of the problems that have arisen, particularly in regard to suspension systems. The modernization of fleets commenced with four-wheeled wagons and progressed to 100-ton bogie vehicles. Some future trends are forecast in relation to the contribution the private builder can make in the manufacture and design of modern freight stock.
