I understand how maybe off-the shelf subways may save costs when purchasing new subway cars, but I think the operational efficiencies and flexibility that a connected system of subway lines with the same gauge would be much greater. I think have more connections and redundancies wouldn't be too bad, especially when the system experiences a problem somewhere, subways could be routed around the system easier.
You could say the same thing about the Transit City network vis-a-vis the legacy streetcar system.
