This line, part of Erie Railroad's Caldwell Branch, ran roughly southwest from Great Notch (Little Falls), through Cedar Grove and Verona to Essex Fells. The line crossed Pompton Avenue (NJ Route 23) on a deck girder bridge; the bridge still stands and is shown facing north from the street and facing west on the right-of-way. There are concrete steps leading up to track level adjacent to the bridge, they were likely used for a commuter train stop at one time.
This short branch is shown in the 2007 SPV atlas as being abandoned as "Erie", so it must have been abandoned prior to the Erie-Lackawanna merger of 1960.
In Verona, the line crossed Durrell Street at grade. Bahr Lumber on that street had a freight spur; track remnants are still in place there. The northeastern end of the line is used as a biking/hiking trail, although it has thick foliage.
