Metro's continuing stray current headache
Metro's still trying to fix the problem of stray current leaking from its light rail tracks into the ground, potentially leading to the corrosion of anything metal underground. Metro learned of the problem last year from CenterPoint Energy.
Credit for this continuing sunshine goes to Tom Bazan, the Chron's Rad Sallee, and KTRH-740's Brent Fuller for not allowing Metro to sweep this problem aside:
Metro and the Texas Department of Transportation say the stray current poses no danger to such steel-reinforced concrete structures as freeway overpasses.
But because that issue has been raised by others, Metro recently asked TxDOT for permission to test steel in its bridge foundations at the Pierce Elevated, Southwest Freeway and South Loop. The three freeways pass over the rail system.
You go, Tom!
