TORRANCE, CA — Several Union Pacific Railroad routes to and from the Los Angeles Basin were temporarily closed due to flooding, landslides, and washouts following the recent torrential downpour. However, the Union Pacific coast route through Santa Barbara and La Conchita, which carries vehicle rail shipments from the NUMMI Fremont, California assembly plant to Phoenix, Houston and Memphis, may be out of operation until late February. Currently, there are some 80 miles of damaged track in that area.The second route that is problematic is the track between Las Vegas and Salt Lake City. There are some 23 washouts and 30 miles of damaged track in the Caliente Canyon area, near the Nevada/Utah border. Union Pacific has been able to survey the damage by air only, as the access roads are washed out as well. UP estimates that this route could be out of service until early February.
