Old and new Caltrain trains at SF station.

The passengers next to me are discussing FPGAs so clearly I'm on
Caltrain.

Woman exiting Caltrain managed to navigate steps on crutches and squeezing iphone on shoulder.

No head end power on my Caltrain but doors and intercom still work. Interesting there is a separate power source.

Head end power on my morning Caltrain keeps cycling on and off. This could be a long trip...

The Caltrain San Fran station is extra full of crazy hobo guys tonight.

I can see no reason why the Bayshore Caltrain station exists. A political sop to San Mateo county perhaps?

An engineer told me that Caltrain engines without separate head end power are called 'growlers'.

On Caltrain once again.
