This Brookline streetcar is rolling along on private right-of-way in 1966, literally on borrowed time. It would be replaced by a dedicated busway was has failed to post the ridership numbers of the old trolleys.
When Brookline (Pittsburgh) was in it's early development stages, the streetcar promised a long lived rapid transit mode, as it turned out it's bus replacement failed to equal the ridership of the streetcars.
In Jacksonville the original proposal in 1980 was for a historic, vintage streetcar line. It was explained to the city that new streetcars could use the same system at a future date. The idea was mocked and JCCI told the city that the streetcars 'must' operate in a street, that they are slow and outdated. Of course it was a set up deal, the Skyway was going to be free.
