[4] The New York, Ontario and Western Railway closed the gap between DeRuyter and Cortland; the CC&D had trackage rights over this route and later leased it.

[9] The potential of the EC&N to provider feeder traffic for its new line intrigued the Lehigh Valley, which purchased the company on February 20, 1896.

Under the Lehigh Valley, the EC&N's Elmira–Camden line was known as the Elmira and Cortland Branch and managed as part of the railroad's Auburn Division.

[13] The Lehigh Valley abandoned the section between Van Etten and Spencer, New York in 1933, as it was redundant to the parallel Ithaca Branch.

[14] Abandonment of the section between Horseheads, New York and Van Etten followed in 1938; thereafter, Lehigh Valley trains required trackage rights over the Erie to reach Elmira.

[17] A washout in June, 1972 from Hurricane Agnes damaged the route between East Ithaca and Freeville, New York, which the bankrupt Lehigh Valley decided not to repair.
