Broad Agency Announcement (BAA) 2019 e-FlyerA Theory for Track Maintenance Life Prediction
The objective of this study is to develop a methodology for predicting cumulative permanent deformation of track structures under traffic loading as a basis for maintenance life determination. This report presents the progress achieved in the second year of the research. A computer model named...2017 Grade Crossing Research Needs Workshop
In August of 2017, the Federal Railroad Administration (FRA) held the fourth Highway-Rail Grade Crossing Safety Workshop in St. Louis, MO. The workshop brought together national and international subject matter experts to collaborate, identify, and prioritize specific research needs. The attendees...Railroad Implemented Countermeasures to Prevent Suicide: Review of Public Information
The public discussion of railroad safety initiatives can help to improve safety, either directly with the public through an increased awareness, or by encouraging other carriers to consider similar safety efforts. Rail carriers are often quick to promote trespass and crossing safety efforts,...
