Abstract
The first Automated People Mover (APM) Systems were pioneered and placed into passenger service in the early 70s. Since the 70s, numerous systems have since been constructed all over the world from simple shuttles to complex pinched loop systems with automated coupling. Some of these early systems have recently been upgraded or replaced. However, the majority of APM systems share the common issue that they are aging and are approaching the end of their initial design life. As the APM systems get older it is important for owners to anticipate the near and long term challenges that will likely be faced. These challenges may be in the form of mechanical systems reaching the end of their useful life, degradation in reliability with the accompanying increase in maintenance costs, or increasing or changing passenger service demands. The decisions on the scope of an aging system upgrade may range from replacement of selected system components to complete vehicle refurbishment or entire wayside system replacement. This paper explores the challenges of maintaining these aging systems and explores the upgrade or replacement decision process and alternatives. Case studies will be explored for APM System refurbishment or replacements as part of the following projects to illustrate how other owners have undertaken the challenge of upgrading or replacing their aging systems.
