DENVER'S LIGHT RAIL LINE

New Orleans kept its 1920s street cars running.  San Francisco still operates PCC trolleys.  But in Denver, Colorado, all the street car lines were abandoned and the rails removed from the streets in the 1950s and 1960s.  So when Denver political leaders decided to reduce auto traffic congestion with rail transit, an entirely new "light rail" line had to be built and equipped from the ground up.  (Photo: the Denver skyline at sunset.)
