Video Imaging For Wayside Condition Monitoring of Rolling Stock
Video imaging technology can be used for real-time condition monitoring of rolling stock without the need to take wagons out of service for inspection. Video imaging removes the need for ore car examiners to manually inspect each train on arrival and departure. This method is not only cost-effective, but also removes human error that may occur during manual checks. The system provides real-time monitoring and analysis, as well as trending.

Automated Rolling Stock Maintenance: Integrated Systems
The ideal system for rolling stock operators uses a range of technologies that can be combined into a single system with interrelated modules. Furthermore, an integrated system should gather and assess a range of parameters that are interrelated and should not be looked at in isolation. Lynx has been working over many years towards such a system. This paper presents some of the advances made by Lynx in this area and explains our philosophy of a fully automated system for rolling stock maintenance.

Wayside Systems for Safer Railroads
Wayside monitoring systems can provide round-the-clock safety checks for certain components. The wayside system described in this paper is used by a major private railroad operator to conduct condition monitoring audits for trains at full operational speeds of up to 75 km/hr. The system checks for presence, damage and wear of critical components on freight wagons round the clock. Since rolling stock components are monitored frequently, the system also contributes to reduced maintenance costs as well as enhanced safety.

Wayside System Combining Wheel Management and Safety Audit
This paper presents a fully automated Wheel Management System (WMS) that measures important wheel parameters at high train speeds and provides up-to-date information on the current condition of wheels. The system checks wheel parameters that are difficult or impossible to see in normal operation. The information is assessed automatically as soon as it is received. Critical measurements are flagged for immediate attention. All historical information is retained by the system, which allows the user to develop better maintenance strategies for wheels and wheelsets.

Cost-effective Strategic Deployment of Interconnected Automated Inspection Systems
Automated inspection technologies currently available are of great benefit in ensuring safe and cost-effective train operation. Placing a variety of inspection systems at strategic locations along a rail network and interconnecting them through a central control interface will improve operational efficiency and increase safety. However, the cost of implementing such systems is an important consideration, and cost minimisation can be achieved by identifying critical operational pathways and implementing a deployment plan that fulfils the requirements of all stakeholders. This paper presents a system integration concept for automated inspection systems, using a typical rail network as an example.

Identifying Misbehaving Bogies — Expert Software For Complete Automated Bogie Care
“Misbehaving” bogies are dynamically unstable bogies that can affect not only vehicle and equipment performance, but can also cause infrastructure damage and derailments. Dynamic instability of bogies is caused by a range of factors, including incorrectly aligned wheelsets. The primary manifestations of dynamically unstable bogies are hunting and tracking. This paper presents a method of auditing bogies automatically by using an expert system software called Bogie Care that ties in with machine vision technologies and sensing devices. The benefit of this method is its ability to identify severely offending bogies, as well as bogies that are just beginning to show dynamically active behaviour.

Dual Dump Wagon for BHP Billiton Iron Ore
BHP Billiton needed to replace damaged bottom dump wagons for its GML line, which is due to close in approximately three years. BHPB needed to maintain production, but did not want to expend capital money on new bottom dump cars that would soon become obsolete. It was therefore decided to design a wagon with dual dump capabilities that could be used first on the GML line and later modified for the MNM line, which had rotary unloading facilities. The dual dump wagon was based on the proven new design currently in service on the MNM line.

Car Care: Expert System for Railway Fleet Maintenance Management
Car Care is an expert system software that helps manage the structural maintenance of railway fleets. This expert system consists of several modules and uses a data base listing the parameters of each car in the fleet. Measured data, combined with statistic, probabilistic, and theoretical models are used to assess the structural condition of each car in the fleet. The program assists the fleet operator in selecting cars that need maintenance at a given time.
