MAINTAINING THE INTEGRITY OF A MASS TRANSIT SYSTEM DURING MAJOR ASSET REPLACEMENT

This article describes how a new Automatic Train Control (ATC) system was phased in, while maintaining the safety of the existing system in operation. The work was done on the MTR underground railway in Hong Kong. To meet rising passenger demand, it was necessary to reduce headways between trains, and thus replace the ATC system. The main objectives of the new ATC system are to: (1) maintain or improve the existing safety level; (2) reduce maintenance costs; and (3) increase service reliability and availability. The MTR Corporation (MTRC) commissioned a series of studies on selected systems, to ensure that each of them could be installed and operated safely. The main studies were safety audit, safety analysis, adaptation study, reliability and maintainability study, operational impact study, and performance study. The MTRC specified system performance, while the supplier was responsible for system design and implementation. The supplier had to provide a system which could be demonstrated to meet the defined safety level, objectives, and requirements. The MTRC produced a project safety plan to ensure that all safety management procedures were in place. The new system had to be interfaced with many existing systems, including rolling stock, track, and telecommunications.
