Exceeding the speed limit would be my guess. It's rounding a corner after coming down a hill. Plus, the tracks were wet as it's been raining here lately.

It was probably a Cal Train commuter unit, the engine could be at either end, they don't turn 'em around anymore. The passenger cars are two level, so they use the full cross sectional height profile.

At 35 MPH the wave front effect would be noticeable, they usually run about 50 where allowed, they can run faster.

Depending on schedule, they do not stop at every station, and in the express section of a run can easily be at 50 MPH fairly near a station they are not scheduled to stop at.
