Nobody is going to accidentally load a large tank (say) from Chemtura on a Schnabel and bring it down through Waterloo.
You say that, but it could happen! And so, it must be accounted for. An overheight load would destroy the OCS, as well as pose a huge safety concern.

I too am curious what the sensing technology is. Hanging horizontal bar with a limit switch? Through-beam photo sensor? It has to be robust and able to handle the weather.
Next time I'm driving up there I'll poke around and see if I can't figure out how to get to the existing gantry setup - or bring my 600 mm and just take the same shot from Northfield.
