A quick clarification to point out: that map is actually by a very talented man named David Cole. His “Metro Cincinnati” concept (and the associated website) were part of a thesis project he did where he (in great detail) envisioned a full fledged regional transit system for the area.
As for the actual plan (known as “Metro Moves”) in 2002—it would’ve differed quite a bit from the map above. Cole’s plan envisioned heavy rail and infrastructure based on the Washington D.C. metro system. Metro Moves would’ve been light rail and while it was ambitious and could’ve served the whole region—the original proposed funding mechanism would’ve been focused solely on Hamilton County. I.E. Had it passed and been implemented to full vision—there likely would’ve been other political hurdles in order to have trains running out of Hamilton County into places like Warren to serve Kings Island (which most likely would’ve served the Kings Mills highway exit area rather than the park directly).
It’s also important to note that this plan called for expanded “hub and spoke” bus service. I.E. The idea was that instead of the downtown-transfer centric bus system we have currently, buses would connect to regional nodes (imagine going from West Chester to Kings Island without going all the way Downtown first). Some of those ideas have been carried over to the “Reinventing Metro” plan currently in planning..
I could go on for days and days about the history of this whole project, but I’ll end on this fun fact:
In the original vision for Metro Moves, the first line to be built would’ve been a downtown circulating streetcar that would share tracks with light rail vehicles bound for the nearby neighborhoods and suburbs. What’s today known as the “Cincinnati Bell Connector” modern streetcar is based heavily off of the original Metro Moves plan (with some changes made to accommodate how Downtown/OTR grew compared to how folks thought they would grow in 2002). The Connector actually uses light rail vehicles currently and its existing tracks could accommodate future light rail transit if a plan were to come about.
