Canarsie & Rockaway Beach 2-4-2 "Columbian" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class Brooklyn (Locobase 16619)

Data from "Brooklyn Excursion Railroads", Railroad Gazette, Volume 9 , (10 August 1877), pp. 365-366. See also "The Brooklyn and Rockaway Beach Railroad Company--the Canrasie Line."

Incorporated in 1863 and opened in Fall 1866, the B&RB's four-mile (6.4 km) line ended at Canarsie on Jamaica Bay where a steamer took the passengers to Rockaway Beach itself. Like other Brookyn excursion routes to the beaches, the right-of-way on the B&RB was relatively lightly built and laid with 45 lb/yard (22.5 kg/metre) rail segments linked by "a very miscellaneous assortment of joints for so short a line." It followed the "very undulating profile for this region of Long Island" and even sported a 3-foot (91 cm) deep cut that ran "800 or 900 feet [244 or 274 metres] long."

It was a busy line with the engines running 14 round trips daily totalling 112 miles. Sundays often meant seven-car trains carrying 800 passengers. RG's writer noted that the B&RB carriee about 1,000 passengers per weekday "with 3,000 or over on pleasant Sundays and holidays." He commented on the "peculiar disadvantage" of having to run two round trips for each train-load, because virtually all of the passengers would head toward the beach in the morning and from the beach in evening. He estimated that the cost per passenger moved increased at least 30-40 percent.
