CALDWELL BRANCH CUSTOMERS:
At the time of abandonment, Overbrook Hospital (Cedar Grove; in service but seldom used); Bahr Lumber (Durrell Street, Verona); West Essex Building Supply (Depot Street, Verona); Caldwell Team Tracks (Caldwell station); Roseland Lumber (Harrison Avenue, Caldwell; connected but overgrown); the Morristown & Erie Interchange (Essex Fells). The Caldwell team track served a variety of off line customers, as well as Roseland Lumber in the end.
Add to the above previously abandoned sidings: W.P. Johnson Coal & Oil (Fairview Avenue, Verona); Slayback-Van Order Lumber Company (Oak Lane, Caldwell just off the Caldwell Yard); Harrison Feed and Speer coal company (both on Harrison Avenue, Caldwell).
In the deep, dim past there was the Francisco Brothers Quarry (Francisco Avenue, Great Notch before 1925); a branch to the Cedar Grove Reservoir (Bowden Road, Cedar Grove 1901 to circa 1905); Overbrook Team Track (Overbrook station dates??); Newark City Home siding (Fairview Avenue, Verona 1890's to ??). Slayback Brothers also had a siding at the Bloomfield Avenue grade crossing in Verona, prior to the grade crossing elimination which caused their relocation to Caldwell yard. Overbrook Hospital may have had a siding that ran from Durell Street in Verona through the hospital grounds paralell to Fairview Avenue to facilitate the construction of the 1920's addition. This is in addition to the known siding to the power plant and commissary. The stub of this was in service opposite Bahr Lumber until 1959.
Other than this, I know nothing.
