District of Columbia
A PCC on Route 42, at Union
Station, looking west, operating on conduit plow trackage. All track within
the inner city was powered by conduit in the street to avoid unslighly
overhead wires. Interestingly, a similar “third rail” system recently opened
in Bordeaux, France using a high-tech third rail in the center of the two
running rails but controlled by computer boxes that only allows the third
rail sections to be energized under the light rail vehicle as its passes.
The track before and after is electrically “dead” until the LRV uses the
next section or leaves the one behind it.
