The tractor/double-trailer vehicle combination known as the c-train is distinguished primarily by the double drawbar dolly connecting the two trailers. this use of this c-dolly eliminates one point of articulation, which has a positive effect of vehicle performance. the self steering axle used by the c-dolly is the focus of most of the remaining concern regarding the c-train and its performance. this report examines the c-train and the c-dolly and its component parts with a view to identifying what performance regulations would be appropriate for encouraging a balanced development of the c-train within the context of interprovincial transportation. a detailed theoretical analysis is presented on the mechanics of self steering axles and their effect on vehicle handling. this analysis is complemented by a practical analysis based on past experience, the effects of design change, and records of satisfactory and non-satisfactory experience. finally, the study presents a set of recommended regulations and outlines a test procedure to prove compliance with the regulations.
