Electrification of Caltrain Introduction
The CalMod is a $1.9 billion project that will modify the train system, and electrify the main line of the U.S. commuter railroad Caltrain, which serves cities in the San Francisco Peninsula and Silicon Valley, a ,major part of the project is the transition from its current diesel-electric locomotive powered trains to electric multiple units (EMU). According to Caltrain, electrification of the tracks will allow it to improve service times via faster acceleration and shorter headways, reduce air pollution and noise, and facilitate a future railway tunnel into downtown San Francisco's Transbay Transit Center.
