Of the 73 California stations served by Amtrak, Oceanside was the fifteenth-busiest in FY2010, boarding or detraining an average of approximately 800 passengers daily.
Oceanside Transit Center was built in 1984, and serves as a replacement for a 1946-built Santa Fe Depot, which was torn down in 1988. The former station was itself a replacement for an 1886-built Santa Fe Depot.
To enhance the regional transit service, this station will have major expansion including building a third track and platform in the middle of the existing tracks, extending all platforms and adding a passenger walkway. The construction will begin in 2014 and is expected to be completed in 2015.
