This little webpage is designed to fix a single problem with Caltrain: the predicted arrival times suck for late trains. Caltrain optimistically predicts that late trains will catch up to the timetable at the rate of several minutes per stop. In reality, late trains stay the same lateness.

So, this webpage takes Caltrain’s predicted train arrival times, and updates them to be less optimistic.

The page requires the last 4 characters of an API key. These characters are “eb0b”.
