What is 2011 Stray Current Corrosion Evaluation about?

This document summarizes the 2011 evaluation of the stray current corrosion control system for the Valley Metro light rail system in Phoenix, Arizona. Key findings include: 1) Track-to-earth resistance measurements along the mainline and yard tracks ranged from 103.7 to over 1,000 Ohms per 1,000 feet of track, meeting acceptance criteria. 2) Pipe-to-soil potential measurements at 10 water pipelines and 2 gas pipelines showed very low interference, similar to 2010 results. 3) Track-to-earth potentials and t
