Project Spotlight: Bay Area Rapid Transit (BART) Rail Monitoring in Transbay Tube

Monitored dynamic shear strains and displacements in steel rails and concrete ties for up to 280 train passages per day through the Transbay Tube under the San Francisco Bay

SS4 Modules mounted in vertical and horizontal directions (both sides of rails)
