Ontario Eastern Railroad

The Ontario Eastern Railroad was a shortline freight railroad formed in 1981 to operate a portion of the former Rome, Watertown and Ogdensburg Railroad from Ogdensburg to DeKalb Junction. The primary freight customer was a paper mill located in Ogdensburg. When the mill shut down in 1985, the railroad ended operations. Formal abandonment followed in 1987 and the tracks were scrapped.

Subsidiary Jersey Southern Railroad (JSRW) was also placed under ONER management. The JSRW operated a four-mile branch line in South Deerfield, New Jersey, to serve a frozen foods plant. Both lines were affiliates of the Ontario Lines group of shortlines.
