There are several safety questions associated with operating passenger trains and freight trains on shared-use rail corridors (SRCs). Among them are adjacent track accidents (ATA) in which derailed railroad equipment intrudes upon (“fouls”) adjacent tracks and is struck by another train on adjacent tracks. ATAs can occur in any multiple track territory, but they become…

The need for shared freight and passenger rail corridors in the United States is increasing due to the growing demand for regional and intercity passenger transport. Several researches have been conducted on reducing the risk of freight train accidents, but little research has been done on the risk of passenger train accidents. The accident rates…

Highway rail grade crossing safety has improved considerably in the past two decades. Among the reasons is investment in more effective warning systems. Such upgrades are costly and resources are limited so decisions on which crossings should receive these investments should be made so that they will have the greatest impact on improving safety. A…

Freight train derailment rate has declined substantially over the past decade. Although various aspects of this improvement in train safety have been studied, there has been only limited research examining the effect of train loading condition on derailment occurrence, causes and severity. Unit trains operate loaded in one direction and return empty, and their operation…

Adjacent track accidents (ATA) primarily refer to train accident scenarios in which derailed rail-road equipment intrudes upon (“fouls”) adjacent tracks and is potentially struck by another train on an adjacent track. ATA has been identified as one of the most important safety issues on shared passenger and freight railroad corridors. Various infrastructure, equipment and operational…

The current methodology for prioritizing level crossing (LC) warning system upgrades and elimination in the United States (U.S.) focuses on the likelihood of collisions between highway and rail vehicles as well as highway user fatalities. However, these metrics do not encompass all LC risks. In particular, they do not consider the risk of derailment that…

Each year the North American Class 1 railroads spend billions of dollars on track maintenance. Even a small percentage reduction in maintenance costs, could save the railroads millions of dollars. Of course this is only feasible if cost reductions can be accomplished without decreasing the safety, utility, and robustness of the railroad track infrastructure. One…

There are potential interactions among approaches to reduce or prevent certain accident causes. Given the overlapped safety benefits of various measures for accident prevention, it is necessary to identify their interactions and quantify the safety effectiveness of combined accident prevention strategies. This study focuses on strategies to prevent broken rails and broken wheels, respectively. Improved…

Annual safety statistics published by FRA provide train accident counts for various groupings, such as railroad, accident type, cause, track type and class, train length, and speed. However, hazardous materials transportation risk analysis often requires more detailed accident rate statistics for specific combinations of these groupings. The statistics that are presented enable more precise determination…

The environmental impact of a hazardous material spill is a complex function of the material’s physical and chemical characteristics and the local environmental conditions in which it is spilled. This study develops a geographical probability distribution for two important environmental parameters affecting this impact: soil type and groundwater depth. The paper assesses the probability of…

Fuel spillage during locomotive refueling is expensive, as is maintaining spill collection and containment systems, and waste treatment costs. The Association of American Railroads has developed the first standard for a locomotive refueling system for North American railroads. The locomotive fueling interface standard is an open, non-proprietary standard designed to prevent fuel spillage. Prototype equipment…

In response to public concerns about the environment, regulatory requirements for cleaning up spills of certain chemicals have become more stringent and cleanup costs have increased dramatically. Hence, due consideration must be given to environmental sensitivity as an element of transportation risk. Among the environmentally sensitive chemicals of most concern to the railroad industry are…

This paper considers the effect of train speed on railroad hazardous materials transportation risk. A statistical method was developed to estimate the speed-dependent conditional probability of release (CPR) of hazardous material from tank cars involved in accidents. The objective was to assess how accounting for speed affects the results of risk analysis. A case study…
