That's good work, Glatt, but I'm not *entirely* convinced. Maybe the track is raised so the driver can see over the green areas beside the track. Does the driver sit on the left, right, or center of the train? Is the seat elevated? How are the pylons on the bridge aligned? What angle was the sun coming from?
There are so many possible sources of minor error that a couple of little things like this could add up to seriously affect the calculations.
That said, you figures are probably in the ballpark.
To me, two facts stand out - the investigators say the brake pedal had been pressed down, yet passengers report feeling no braking.
Add that to all that stuff about old train cars with poorly maintained brakes, and I'm happy to jump to a conclusion.
