Cincinnati's Abandoned Subway

But I've been frustrated for the past forty years trying to find more. Current employees working for the city know nothing about it. My Dad watched the construction as a junior high student. The newspaper story about the illegal tour was the only confirmation I've ever seen.
If not any of those, I'm curious what the historical societies or maybe some offbeat publication like the Motor City Muckraker might be able to dredge up.
Tried the archive just now and couldn't find anything around the time of the actual construction but I will keep working on it.
If I can find a little bit bet I could get the Muckracker to do a story. Bet they have resources we both lack.

The new one was built as part of the Fort Washington Way rebuild.

Mostly due to location no longer suitable, ie too close to another station, or issues with access. Or structurally unsafe and uneconomical to refurbish, maybe some was damaged too much from the Blitz.
And not all are passenger stations. Some were for maintenance, post etc.
Royal Mail did have its own tube line: https://en.wikipedia.org/wiki/London_Post_Office_Railway
The division of responsibilities between the rapid transit and commuter rail systems in DC and the Bay Area is different in a way that might account for both the greater total system length and the lower ridership per mile compared to Chicago's system. Or Boston's T, for that matter.
It's hard to tell if the lack of the subway was a factor in the lower rate of growth or if the lower rate of growth meant the subway wasn't needed after all.

I think it likely if the streetcars had grown, they probably would have been converted into subways, etc. and more extensive public transit generally..
although postwar prosperity probably helped as well (whereas europe had to rebuild)
The Blue Line is underground for probably about the same distance (goes under South of Addison and then hits the Loop, heads West, and reemerges West of Clinton).
My estimate might be a bit off, I'll just going off my mental map of the city.
Cincinnati is pretty hilly - not San Francisco or Seattle hilly - but enough that I would think developing any sort of system would be pretty expensive and difficult.
