Amtrak #738, the Capital Corridor, makes a stop at Martinez, California.
I have been looking for moving targets to practice pulling focus while operating the camera - not an easy thing to do. I've been doing some research on a follow focus system and the Focus One Pro by Edelkrone looks pretty good. I like how the marker disk faces the camera operator.
