Improving rail performance

MTR Corporation operates one of the world's most densely utilised urban mass transit system with high expectations for service reliability from the customers. As a result demands on the track and its management are high. On its 43.2 route km Urban Lines it carries 2.3 million passengers per day and has annual tonnages of traffic of over 45 million gross tonnes on one track. MTR recently has opened two new lines, operating at 135 km/h. One, the Airport Express Line provides a high quality, limited stop express service to the new Hong Kong International Airport on Lantau Island. The second, the Tung Chung Line provides a mass transit service from central Hong Kong to the new town of Tung Chung. One of the key components of the track system is the rail. Continuous improvement in the performance of the rail is necessary to ensure a safe and reliable permanent way which can meet the increasing demands placed on it in a cost effective manner. In this paper the authors describe the holistic process which MTR Corporation, with technical support from BHP Research Melbourne Laboratories (now BHP Institute of Railway Technology, Monash University), has adopted for improving rail performance with respect to selection, profile deterioration, corrugation growth management and wear rates. The paper contains specific examples of the technical performance of the rails on its Urban Lines and the benefits achieved through the process, some of which challenge generally established expectations concerning wear rates. The results identify the actual improvements in performance achieved through implementation of a rail management model and the adoption of heat treated rails. The initial rail performance of the Airport Express and Tung Chung Lines is reviewed and predictions for the future made. The authors conclude with a consideration of the merits of the process adopted by MTR Corporation and its expectations for future improvements.
