This is why I asked what routes outside of existing right-of-way would you persue. I think a north crosstown or north 270 ring line would be a good/necessary addition.
I'm also of the mind that streetcars wouldn't cut it for those distances. If I need to get from, say near Morse and 270 to my job at say.. Sterling Commerce Near Tuttle, a streetcar line would take forever and have too many stops.. whereas a light rail would be competitive with the time it takes to drive.
Yeah. Streetcars or "local service" buses are not good for cross town.
However, these existing rail lines do have junctions beyond what is shown here. If you look on google maps you will see, for one example, that there is an exising rail pathway between the airport (at hamilton road) and worthington.
Part of the problem here is that there are significant topographic constraints on running a line from, say, gahanna directly to dublin, so the freight rails all run north/south to downtown where the river valleys converge and a freight rail line can go back uphill to dublin from there following the river valley where the grade is reasonable.
Passenger trains can handle hills better, but none of our existing rail lines are built for that purpose. A pair of rails running along 270 east and west on both ends of the city would be a lovely idea to build later, but they would be purpose built for light passenger service. A freight train would have a hell of a time going uphill along 270 for example eastwards from sr-315 to sr-23.
