GTW/CN is really the solution to our transit problems. We need a downtown depot. MCS is not convenient to downtown like Brush St was. From Brush St you have the line out Woodward to Pontiac, the line out Gratiot to Richmond, and a convenient connection to the old Michigan Central line out Stephenson to Utica.
It would take some track work to move the western trains from Ann Arbor [[Michigan Central) or Brighton [[Pere Marquette) into downtown.
You could run light rail on heavy rail routes, something like the old Budd RDC cars

or the more modern DMUs.
