The Schmidt-Henschel boiler was replaced with a tapered boiler, with a drumhead smokebox, designated type 2. [1] The type 2 boiler had a tube surface of 1,669 square feet, formed by tubes 2 + 1 ⁄ 8 inches (54 mm) in diameter and 14 ft 3 in (4.34 m) long. [2] It was fitted with a 28-row superheater with 360 square feet (33 m 2) of heating ...
However, they had larger boilers and smaller cylinders for higher working speeds. Twenty were built in one batch and numbered between 1113 and 1195. Originally built with saturated boilers pressed to 175 lbf/in 2 (1.21 MPa), seven locomotives were later fitted with boilers equipped with superheaters and pressed to 160 lbf/in 2 (1.10 MPa).
It was the longest steam locomotive that was ever built. [1] The unit looked similar to the C&O turbines but differed mechanically; it was a C+C-C+C with a Babcock & Wilcox water-tube boiler with automatic controls. The boiler controls were sometimes problematic, and (as with the C&O turbines) coal dust and water got into the electric traction ...
William Dean, Armstrong's successor, designed (among others) four classes of locomotive, 2-4-0 and 0-6-0 tender and tank engines, which shared many standard components. However, it was Churchward who carried the policy to lengths which made GWR locomotives distinctive and shaped their development until the nationalisation of the railways .
A fire-tube boiler exploded at the Grover Shoe Factory in Brockton, Massachusetts, on March 20, 1905, which resulted in the deaths of 58 people and injured 150. Then on December 6, 1906, a boiler in the factory of the P.J. Harney Shoe Company exploded in Lynn, Massachusetts. As a result, the state of Massachusetts enacted the first legal code ...
The 17 1/2 cylinder and 4 ft. 7 1/2 in. wheels diameters of the later '2721' class were adopted and the leading frame overhang was extended from 4 ft. 9 in. to 5 ft. 6 in.; the frames were strengthened (and altered in configuration to 'marry up' with the longer smokebox, unlike the '1854' rebuilds) and the injectors, valances, and wheel centres ...
When new, all were provided with LNER Group Standard (G.S.) 4,200-gallon tenders (a type of which more than a thousand were produced between 1924 and 1952) having a water capacity of 4,200 imperial gallons (19,000 L), a coal capacity of 7 long tons 8 hundredweight (8.3 short tons; 7.5 t) and a wheelbase of 13 feet 6 inches (4.11 m); all were equipped with water scoops.
The Caledonian Railway 812 and 652 Classes were 0-6-0 steam tender locomotives designed by John F. McIntosh for the Caledonian Railway and introduced in 1899. They had the same boiler type as the 721 “Dunalastair” Class 4-4-0s. They could reach speeds of up to 55 mph (89 km/h). [1]
