Caltrain will be conducting rail maintenance work from Thursday, July 3 through Monday, July 7 in San Bruno.

This work will take place between the San Bruno Caltrain Station and Santa Helena Avenue.

The work involves removing and replacing sections of rail, which may include resurfacing, grinding, and welding.

Because the rail must be replaced in a continuous process, crews will be working non-stop over the weekend to reduce disruption to rail service.

Nearby residents may notice increased noise and activity during these dates.
