OBJECTIVE We investigated the effectiveness of a theoretically motivated intervention at reducing procedural errors in train yard operations, where making these errors could be costly or life-threatening. BACKGROUND A widespread and persistent memory error that people commit on a daily basis is the postcompletion error (PCE), that is, forgetting to complete the final step of a procedural task...

Scholars have long recognized the important differences between the northern and southern rail networks. Business historians focusing on northern enterprises have documented an impressive list of accomplishments: railroads pioneered modern accounting methods; railroads introduced new management techniques and organizational structures; and railroads helped transform national and international c...

BACKGROUND The aim of the study was to summarize bladder cancer risk in motor vehicle drivers and railroad workers using meta-analysis techniques. METHODS We retrieved all published results (3 cohort studies and 27 case-control studies) during 1977-2008. We assessed the heterogeneity of the results assuming a fixed-effect model. For cohort studies, the observed and the expected number of case...

T hirty years ago, our paper entitled “The High Cost of Regulating U.S. Railroads” (Regulation, January/ February 1981) appeared in this journal. At the time, the Staggers Act had just been signed into law. Our paper provided an analysis of the U.S. railroad industry’s performance for the generation immediately preceding the legislation. We focused on the cost of pre-Staggers regulation and dre...

To ensure efficient railroad operation and maintenance management, the accurate reconstruction of BIM models is a crucial step. This paper proposes workflow for automated segmentation structures using point cloud data, without relying on intensity or trajectory information. The consists four main components: adaptive denoising, scene segmentation, structure combined with deep learning, model re...

A bridge approach, an essential component connecting a relatively rigid and more flexible track on subgrade soil, is one of the most common types transition zones. The tracks deck often undergo significantly lower deformations under loading compared to approach tracks. Even though there have been numerous efforts understand remediate performance deficiencies emerging from differences in stiffne...

the main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. therefore, railway track desig...

We describe competition over space between a competitive shipping industry (truck-barge) and one with market power (the railroad). The latter prices so as to "beat the competition" in equilibrium, or else at the monopoly price, if that is lower. The monopoly price rises more slowly than do the costs of transportation (freight absorption) if the spatial demand at each point is log-concave. With ...
