The Canyonero of signals is surely this brawny Made in U.S.A. signal gantry mounted on top of the San Bruno grade separation. The gantry (probably a standard two-track gantry, to save money!) was too wide to be mounted in this location, so two cantilevered concrete platforms, seismically worthy, were built on each side to support the gantry and keep out any terrorists. [UPDATE: check out the engineering drawing!] If that wasn't enough, this signal gantry needed its signal house (probably a standard 8'x8' signal house, to save money!) perched on top of the opulent platform as well, with classy electrical conduits slung underneath and a dedicated ADA-compliant staircase allowing maintenance personnel ready access. Maybe they were trying to save some parking spaces by suspending everything, but the entire area had to be fenced in for security.

Oh, and the new speed limit at the San Bruno curve, the #1 worst curve on the entire peninsula? 65 mph, up from 60 mph before. It could have been 100 mph if this project had been conceived intelligently.
The concrete has been poured, and this installation shall now and forever stand as a monument to our Transit Industrial Complex, as it embarks on far more challenging endeavors such as electrification, level boarding, the downtown extension, and maybe some day high-speed rail. The symbolism is hard to avoid.
