Top Rail & Outrigger

The red blob is a 2.25-inch copper conductor large enough to employ 750V power substations about three miles apart. It is protected inside the massive steel pipe. Smaller red conductors, nearly surrounded by insulation, distribute power to each train. This "under-running third rail" applies the very best rail transit practice. The aluminum guard is discussed elsewhere.

Outrigger details at the right are for discussion with specialists, but notice that the steel outrigger frame encircling the railhead couldn't come loose even if all the rollers should fail. Other views of the outrigger are in the "car" group of pictures.
