The effective date was probably April 1, 1976, Conrail start-up day.
The owners of the D&M bought the property as a real estate play.
They were chagrined to find out MIGN intended to use the boat.
The state paid D&M a subsidy to switch the boat and manage it.
That was logical as D&M owned the boat slip.
The state owned the boat as no one else wanted it.
Toward the end, MIGN formed a subsidiary, Boat Company, to manage the boat.
To my knowledge, D&M continued to switch the boat and was paid by the state.
D&M ultimately got what it wanted, property with no railroad track, suitable for development. MIGN just delayed things.
