Commuter trains have been running between San Jose and San Francisco since 1864. The trains are currently operated by Caltrain. In 2004, Caltrain completed the largest upgrade in the line's history. The project, know as CTX, added all new signals, and a lot of new track.
The collections at right show the signals before and after the CTX project.
The three miles of track between San Jose and CP Coast were not effected by the CTX project. They are covered in the Coast Starlight section.
On each page, you will see descriptions such as this:
