Trains headed inbound from O'Hare would turn south under Clinton or Canal St, stop at Union/Ogilvie and then turn east following the path of current trains from Forrest Park they could then run back south at Clinton or Canal St and west to Forrest Park (completing the loop).

Or the Blue Line could be split into two operating services (O'Hare, Loop, back to O'Hare and Forrest Park, Loop, back to Forrest Park).Ah, there ya go. Much better. That way, you could have two track service along the new Clinton St. subway with all trains running in one direction (south). One side to O'hare, the other to Forest Park.

No biggie...
