New Thread on Convertible Streetcars

[MidlandMike]

I found this using Google using your spelling of convertible with an "a"

That was explained on the thread that I wanted to pull-up, but was frustrated by the failure of the Search button on the Trains website to work properly, and it did not work for any search, even for current postings.  So here are some photos already posted on the thread I was attempting to reach.   These photos will answer your question.

Before the invention of the convertable, some streetcar systems had two sets of cars, closed for winter use and open-bench cars for summer use, with the latter always requiring two-man crews.

 

Convertables provided a solution and could be adapted for one-man operation, as those Brooklyn, Manhattan, and The Bronx were adapted.

 

More effective ventilation systems for closed cars also solved the problem, later.

My question on 'Convertible' street cars is - what are they converting from or to?

Some more Third Avenue Tranist photos, one giving a comparison between a curve-side, older even with higher number, and a straight-side in the distance.

The seach button on Trains Forum did not work for "Convertables" for me this morning.  It did in the past.
