This is an animation of the weekday Caltrain schedule (as of April 2, 2007).
Trains are shown as red while in motion, and white while stopped at stations. Each train is labelled with its train number. The label's background colour indicates whether it is a local, limited, or Baby Bullet.
The Start/Stop button is used to start or stop the clock. The Reset button resets the clock back to the beginning. The Step button steps the clock by one step time. The Faster and Slower butons increase and decrease the step time.
