Caltrain will be doing routine maintenance on its train tracks from South San Francisco down through the South Bay this week.

Monday through Friday crews will be doing various tasks along the tracks between Atherton and San Jose. The work will take place from 10:00 pm to 7:00 am when the rains are not running. There may be delays in these areas along with some construction noise.

Friday evening at 8:00 pm the railroad grade crossing at Rengstorff Avenue in Mountain View, between the Central Expressway and California Street, will be closed to allow crews to reconstruct the crossing and adjacent track, as well as resurface the street. The temporary closure will take place until Monday morning (March 31) when the track will be reopened for regular weekday train service. Drivers will have to detour around the construction by using Shoreline Boulevard or the San Antonio Road overpass. A free shuttle will be available for pedestrians on Saturday and Sunday from 9:00 am to 5:00 pm.
