Non-contact Deflection Monitoring System for Timber Railroad Bridges

TRB's Rail Safety Innovations Deserving Exploratory Analysis (IDEA) Safety Project 35: Non-contact Deflection Monitoring System for Timber Railroad Bridges summarizes a project that explored the feasiblity of the methodology. Considering the abundance of timber railroad bridges in the nation that have exceeded their design life, a cost-effective and safe deflection monitoring system would be helpful for their regular maintenance.
