I live on a street that used to have a streetcar line on it! Now it's just a stroad and traffic monstrosity but I sometimes daydream of hopping on the streetcar and going to meet up with friends downtown.
I'm in the suburbs but like you an older one and more densely packed. I'm maybe a mile from a major highway that goes to the city center. It's dead straight and major thoroughfare. If they dedicated one line to rail, none of that mixed BS, and had stops say every mile into the city my god it would be amazing.
Are you sure it is more densely packed? Where I live the streetcar suburbs are slightly less dense than modern suburbs. In the 1950s lot sizes went up, but they have mostly come down again. (streetcar suburbs were built assuming you would get some food from your garden. 1950's suburbs were built by/for people who remembered the depression and wanted a large lot for a garden - or that is my theory.
Streetcar suburbs are not 1950s suburbs, they are 1900s-1930s suburbs. 1950s suburbs are car suburbs.
Right, we have all 3, and they have different forms. 1950s is the least dense.
