This paper describes some of the practical engineering aspects in the design of suspension systems (trucks) for railway vehicles. Several important and interesting considerations in suspension design are discussed with particular reference to the LRC coach trucks. The Dofasco power banking truck is a major engineering innovation in the design of the Canadian LRC (Light-Rapid-Comfortable) railway coach. The active banking mechanism tilts the car body on curves an amount which depends on the degree of track curvature and superelevation and train speed, thus ensuring passenger's comfort. The hydraulic banking system which is activated by sensors, allows an effective tilt of the car body of 8.5 deg, to nullify the centrifugal forces at speeds 35 to 40 percent faster than possible with conventional passenger coach equipment. This results in a significant increase of average trip speed. The philosophy of truck design and development is outlined: The various phases of the development include conceptual design, suspension performance, structural integrity, production and testing. The paper also outlines quasi-static and dynamic analyses used to assist in the suspension design. (Peters)
