CB&Q 2-10-4 Class M-4 6312
Title:  CB&Q 2-10-4 Class M-4 6312
Description:  Chicago Burlington & Quincy Railroad 2-10-4 Class M-4 6312 at Philadelphia, Pennsylvania on an unknown day in October 1927, photograph by Baldwin Locomotive Works, Chuck Zeiler collection. Number 6312 was built in October 1927 (c/n 60252), rebuilt to M-4a in January 1940, retired and sold for scrap in May 1961. The following is from the Burlington Route Historical Society's Bulletin 21, 'The Q's Colorado Types', by Hol Wagner:

In the latter part of 1927, the Burlington received from the Baldwin Locomotive Works 12 locomotives of the 2-10-4 wheel arrangement, commonly called the Texas type after the design's origin on the Texas & Pacific in 1925. Numbered 6310-6321 and classed M-4, the Burlington engines (known on the Q as the Colorado types) were the largest and most powerful two-cylinder locomotives built up to that time. They were designed to replace 2-10-2's on southern Illinois coal drags over the Beardstown Division and in doing so to increase tonnage per train, obtain the greatest fuel economy possible and reduce the amount of overtime paid to crews on the slower 2-10-2's.

The boilers of the M-4's were of the radial stay, inverted wagon-top design, 92 inches in diameter at the first stay ring, and 104 inches across at the throat. The barrel contained 87 2½-inch firetubes and 222 3½-inch superheater tubes. The large firebox, carried above the trailing truck, was 150 inches long by 102 inches wide inside the sheets, giving it a grate area of 106.5 square feet. It was equipped with a combustion chamber and arch tubes. Southern Illinois bituminous coal was the locomotives intended fuel, and it was supplied to the firebox by a Duplex stoker. A low steam dome was centrally located on the boiler barrel, and was flanked fore and aft by large sand domes. Engines 6310-6315 were equipped with Elesco feedwater heaters, while engines 6316-6321 had Worthington BL heaters. All 12 locomotives were outfitted with Strombos quadruplex air whistles (actually horns) mounted atop the boiler just ahead of the front sand dome. These air horns were in vogue for a brief period of time during the late Twenties and were applied to a number of Burlington locomotives.
