"OT" to a railroader means you 1) worked more than 8 hrs on a switching job, 2) took more than 8 hours to make a 100 mile pool freight run AND you didn't get any initial dealy nor roundhouse miles (can't make final terminal delay and OT coucurrently either), and 3) spent more time on duty that the time to miles conversion dictated based on a local's bulletined mileage. It looks like he was working mostly switch engines, but not very many are time and 1/2 shifts (possibly only one). There's one local to Suisun, which probably didn't earn any OT because those jobs had such long schedules to begin with.

To quote a friend who worked there in this day, the crew disp once told him "You're 29 times out on the floor, but don't go anywhere we're going to need you", "on the floor" meaning the extraboard was so long, the list reached all the way down below the Big Board to the floor.

Can you reveal the guy's name?
