PROJECT: CORROSION/TRANSIT AUTHORITY
LOCATION: HOUSTON, TX

V&A is conducting annual corrosion control surveys over a three-year period for Houston’s METRO light rail transit (LRT) system. The METRO LRT system is continuing to expand, with new lines and extensions opening in recent years. In addition to the ongoing measurements of stray current on the existing system, V&A has performed corrosion control testing on the new lines and line segments during construction and during the pre- and post-startup phases. This testing includes track-to-earth resistance testing for both electrically isolated and electrically interconnected track segments, holiday testing of rail boot insulators, and baseline measurements of pipe-to-soil potentials on adjacent utility pipelines.
