The LV local from P&L (I believe) outlawed at Quaker 3-31-76 so technically it was an LV train when it went east afterward. As far as I know nothing moved from Buffalo after the last day - I know of at least one speeder trip from Rochester Junction almost to Buffalo (unauthorized of course) and understand the rails were rusty and crossings obstructed with dirt.
CR was designated as the operator of the Geneva-Victor segment under a 5-year program of subsidy to continue operations. About 1977 or 1978, a connection was built between the ex NYC Auburn road just east of Shortsville, allowing trains to run the Auburn Road to that point and then access the old LV westward. Once in place, the LV was removed from service and scrapped between Geneva and Shortsville.
Similarly, a connection was made from the LV at Maple Ave Victor, curving south and east and joining the Auburn Road at the Victor Insulator plant. This connection, little more than a quarter mile long, allowed abandonment of several miles from Canandaigua to Maple Ave Victor on the old Auburn Road.
An interesting item occurred one winter day when a plow was used to clear the former LV. The crew left Victor westbound, and the engineer was moving right along toward Rochester Junction. Someone had missed a bulletin somewhere, and they found out the hard way that the track had been removed a quarter mile west of Route 251. When they stopped, all 4 axles of the plow, and three of the engine's 4 axles, were on the ground. OH S**T!
The ONCT took over operations 10-01-79.
