Caltrain Reduces Weekday Service to Expedite Electrification Construction

From Monday, May 2 until Friday, May 20, Caltrain will temporarily reduce its service levels down to 88 trains per day to accommodate Caltrain Electrification work in San Mateo and Burlingame.

This construction was initially scheduled for March, but was rescheduled as a result of the March 10 incident. Baby Bullet service will be suspended during this period of construction. There will be no changes to weekday midday and evening service, or to weekend service.

Trains will be single-tracking through Broadway, Burlingame, San Mateo, Hayward Park and Hillsdale stations for three weeks, so riders using those stations should be sure to pay attention to signage and announcements to make sure they are waiting at the correct platform at the station.

Approximately between the hours of 5:30-9 am and 3:30-7 pm, three trains per hour will operate in each direction. Due to single-tracking, the number of operating trains has been decreased to three to minimize delays. There will be no local service during these periods, but riders can transfer at mid-line stations to get to their destination.

See train numbers and patterns in the diagram below.
