This study attempts to quantify the economic benefits that the electronically controlled pneumatic brake (ECP) technology can provide the operator of a unit coal train and the owner of the associated fleet. A controlled study over a fixed Northeastern US rail route was performed with two equivalent unit coal trains. The cars of the first train were equipped with the latest generation of an electronic air brake system (EABS), while the cars of the later train remained unmodified, and acted as the control. These two trains made round trips between Southwestern Pennsylvania coal fields and two electric utility plants in Eastern Pennsylvania. Incorporated in the data collection process was the compilation of dynamic train energy measurements from a sample of round trips for each of the two trains, and the collection of repair and service data associated with the cars of each train.

This survey reports on motive power developments for the previous year ending August 1997. Invitations to participate were sent to a large number of locomotive builders throughout the world. Although the response was limited, railway industry trade journals and other rail magazines provided additional input. General information is presented on five diesel locomotives and six electric locomotives.

The travelling public needs to be able to raise an alarm in the instance of personal safety, health concerns or to report an observation about the safety of equipment in their vicinity. The priority alarm system is a means of displaying information to the crew for conditions in their consist of passenger cars, which can be multiplexed on existing train lines.

This paper describes a simple analytical technique for determining the derailment potential of articulated wagons as they negotiate curve entry spirals. The effects of local track perturbations are included. The technique is iterative and analogous to moment distribution. It is implemented using the Mathcad program.

Temperature data from commercial analog hot box detector equipment is digitalized, the mean and standard deviation are calculated for each side of a train and wheels with temperature values above a predefined upper limit are identified as hot boxes. The upper limit is measured in standard deviation units above the mean. The results of the statistical analysis of the heat data, alarms generated by other detection equipment, such as high and wide load detectors, other inspection data, such as train length, direction, and location of the inspection site, are reported to a control site in ASCII over a communication channel.

Activities of the Federal Railroad Administration (FRA) concerning the development of safety standards for passenger railroads that may affect intercity and commuter rail operations. To ensure safety of increased traffic in passenger rail operations, FRA, with the assistance of RSAC, is developing or updating its safety standards on passenger equipment, locomotive cab conditions, track, signal, and train control. The paper sets out the general scope of those standards, in varying stages of completion, in the context of comparable voluntary consensus standards being considered by various working groups of APTA, IEEE, and ITS.

Sponsored by the Transportation Cooperative Research Program (TCRP), project TCRP G-4, Developing Standards for System and Subsystem Interfaces in Electric Rail Passenger Vehicles, was initiated in January, 1996. Its objective was to design a process for developing consensus standards for system and subsystem interfaces for light rail, heavy rail, and commuter rail vehicles and use the process to produce one or more standards. The Rail Transit Vehicle Interface Standards Committee (RTVISC) was formed within the IEEE to serve as the sponsor and balloting group for rail transit vehicle interface standards. RTVISC identified eight key areas for interface standardization and formed working groups to begin drafting IEEE standards in these areas. In October of 1997, IEEE P1477, standard for passenger information system for rail transit vehicles, was successfully balloted. Seven other drafts are well on their way to completion. This paper summarizes the status of the eight standards presently being sponsored by the IEEE rail transit vehicle interface standards committee. The other seven are: IEEE P1473, Communication Protocols Aboard Trains; IEEE P1474, Communications Based Train Control; IEEE P1482, Rail Vehicle Monitoring and Diagnostic Systems; IEEE P1483, Safety Considerations for Software used in Rail Transit Systems; IEEE P1475, Functioning of and Interfaces among Propulsion, Friction Brake and Train-borne Master Control on Rail Rapid Transit Vehicles; IEEE P1476, Passenger Train Auxiliary Power Systems; and IEEE P1478, Environmental Conditions for Transit Rail Car Electronic Equipment.

This paper describes a computer-based automated test procedure for measuring the loop and rail-rail transmission line parameters of rail track. Measurement data from short-circuit and open-circuit tests are subjected to signal averaging to extract noise, followed by Fourier decomposition to extract the amplitude and phase of the fundamental. Sample results are presented for track impedance and admittance in the frequency range 1 Hz to 25 kHz. The methodology is generic in that it can be applied to any track length and any two-rail system including catenary-rail circuits for traction power networks and rail-rail circuits for track signalling systems.

The Massachusetts Bay Transportation Authority (USA) will soon be operating one of the largest fleets of low floor light rail vehicles (LF-LRVs) in the world. The project team has had to meet many challenges presented by the integration of the new design into one of the most severe operating environments in North America. This paper presents a brief historical review of the project, covering the decision to select low floor cars and the resulting car configuration issues. The key challenges to the program and some resulting technical features of the car are reviewed. The approach of the project team to resolving problems is discussed, with experiences of operator, consultant and carbuilder presented. In conclusion, the prototype testing program is discussed, with a review of its objectives and presentation of the results achieved to date.

This paper describes the development, operation, and validation of an automated wayside detector that monitors curving performance of individual rail vehicles. The detector can alert management to derailment conditions and identify cars requiring remedial maintenance. The curving performance data can also be placed in a maintenance database for long term maintenance planning and component life cycle costing.
