SAN FRANCISCO (KGO) -- Commuters beware! BART is testing its earthquake early warning system Monday.
Between 11 and 11:15 Monday trains will slow to 27 miles an hour. Stations and trains will broadcast an alert to passengers to test a real-time ShakeAlert warning.
Following the test, federal and state legislators, BART officials, and UC Berkeley seismologists will hold a press conference to announce the newest version of ShakeAlert.
Serious delays are not expected.
