Beech Creek, Clearfield & Western / Boston & Albany 4-8-0 "Mastodon" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class F-1/H-30, H-30a (Locobase 14263)

Data from "Manufacturers and Supplies," The Railway Age, Vol 26,, No (30 December 1898), p. 958; and NYC&HR 9-1905 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Raildata collection. (Thanks to Chris Hohl for his 10 April 2015 email stating that the HP cylinder diameter should be 22" and for querying the road numbers.) Works numbers were 4922-4926 in January 1899 and 5393-5398 in January 1900.

Ashton safety valves, Detroit and Seibert lubricators, Star Brass company's steam gauges, Westinghouse-American brakes, Midvale tires, Sterlingworth brake beams, '-Magnus" journal bearings, American balanced valves, United States metallic packing, Carbon boiler and firebox steel, Hancock composite injectors, Leach sanding apparatus, Keasbey & Mattison magnesia boiler covering, Trojan couplers, and cast-steel driving wheel centers manufactured by the American Steel Castings company.

Sources report that the operating department did not like this cross-compound Twelve-wheeler design.

The class received new numbers when the B&A's locomotives were brought into the New York Central's overall numbering scheme in 1900. By 1905, the shops had converted the class to simple expansion; see Locobase 15833.


Class H (Locobase 5288)

The data comes from a reproduction of the New York Central's 1902 Locomotive guide found on http://www.rr-fallenflags.org/nyc/ncy-lbp197.gif (visited December 2002).

This class of Twelve-wheelers is virtually identical to the 2-8-0s built for the NYC&HR in the same year. Perhaps the designers went for the bogie rather than the truck to improve the locomotive's stability at speed. Otherwise, there's almost no difference between the two designs.

Staufer (New York Central's Early Power, 1967), p 145, says that Beech Creek's purchase of this series of 4-8-0s is hard to figure except that the arrangement had come into a brief vogue at the time. Besides the Boston & Albany H-30 cross-compounds (Locobase 14263), these were the only Twelve Wheelers the NYC system ever operated, and they were gone by 1915. (See Locobase 5289-5291).


Class H-1 (Locobase 5290)

The data comes from a reproduction of the New York Central's 1902 Locomotive guide found on http://www.rr-fallenflags.org/nyc/ncy-lbp199.gif (visited December 2002).

Twelve-wheelers derived from the H class of 1889, but with taller drivers and longer firetubes. See Locobase 5288 for fuller explanation of this arrangement's appearance on the NYC.


Class H-3 (Locobase 5291)

The data comes from a reproduction of the New York Central's 1902 Locomotive guide found on http://www.rr-fallenflags.org/nyc/ncy-lbp201.gif (visited December 2002).

Twelve-wheelers combining design elements of the HA and the H-1 class. See Locobase 5288 for fuller explanation of this arrangement's appearance on the NYC.


Class H-30, H-30a/R-30, R-30a (Locobase 15833)

Data from NYC&HR 9-1905 Locomotive Diagrams supplied in August 2013 by Allen Stanley from his extensive Raildata collection. (Thanks to Chris Hohl for his 10 April 2015 email offering his road-number correction.)

As noted in Locobase 14263, these Twelve-wheelers didn't remain cross-compounds for very long. The conversion to simple expansion include dropping the boiler pressure. Shortly thereafter, the class was renumbered again to 3632-3642. In 1912, they took 2574-2584 and, after the B&A resumed numbering its engines in a separate sequence, 800-810.

Unloved by their crews, many H-30s were reclassified as R-30 and R-31 switchers in 1913 before being scrapped in 1916 (7), 1918 (2) and 1921 (807 and 810).


Class HA (Locobase 5289)

The data comes from a reproduction of the New York Central's 1902 Locomotive guide found on http://www.rr-fallenflags.org/nyc/ncy-lbp196.gif (visited December 2002).

One-off Twelve-wheeler that increased the boiler dimensions of the H class. See Locobase 5288 for fuller explanation of this arrangement's appearance on the NYC.
