Winds disrupt light rail from Folsom to Sacramento
Buses will be ferrying riders between Folsom and Sacramento on Tuesday due to a wind-caused disruption of light rail.
Regional Transit’s Operations Manager Mark Lonergan said the high winds overnight caused a big section of the power line for trains on the Gold Line between 59th Street and 65th Street to come down.
A fiberglass insulator broke from storm damage, which caused tension in the line to be released, resulting in a lot of damage. The power line came down to the ground along the RT right-of-way and other equipment was broken.
“We are down for probably most of today,” Lonergan said.
A bus bridge is in place from Folsom to 29th Street, virtually all of the Gold Line.
“We are encouraging people to find other transportation alternatives today,” Lonergan said. “Certainly we will have the buses in places, but expect a slow trip today as we work on repairs.”
Crews will be working on the problem during the day, but is unclear if the problem will be fixed by the evening commute.
