An overview of steerable bogies (or trucks) for railway vehicles is provided, along with their potential benefits to railroad operations. Some of the common designs for steerable bogies are reviewed. A NUCARS simulation model is used to compare a three-axle steerable and straight bogie in terms of their curving dynamics in 7.5- and 10- degree curves. The simulation results show that steerable bogies have a substantially lower axle angle of attack and wheel/rail lateral force. Further, the benefits of steerable bogies in terms of increased operational efficiency to the railroads are discussed.
