Caltrain today will begin lowering horn noise from trains passing through certain stations in California.
The railroad chose the stations for horn-use reduction based on their configurations. For example, a train passing through the San Bruno, Belmont and San Carlos stations only needs to sound one short horn blast as it approaches because those stations have track and platforms that are separate from street level.
