When the Aspinall engine appeared in 1899 it leveraged the capability of the 4-4-2 to hold a larger boiler. [5] The length of the boiler increasing from 10 feet 7 + 3 ⁄ 4 inches (3.245 m) in his previous 4-4-0 design while the heating area increased from 1,108 square feet (102.9 m 2) to 1,877 square feet (174.4 m 2).

The Lancashire and Yorkshire Railway (L&YR) Class 8 was a four-cylinder 4-6-0 express passenger locomotive designed by George Hughes introduced in 1908. Design and construction [ edit ]
Twenty of the class, built in 1903, were fitted with Henry Hoy's cylindrical firebox with a corrugated steel inner furnace, inspired by contemporary textile mill boiler practice in the area. The inner furnace was designed to be stiff enough, owing to the corrugations, to avoid the need for stays .
The final twenty examples of the 2-4-2T tanks built between 1911 and 1914 added superheating, long smokeboxes on Belpaire boilers, larger big-end bearings and an increased cylinder bore of 20 + 1 ⁄ 2 in (520 mm) to the modifications that had accrued since 1899. The resulting superheated locomotives had an increased tractive effort of 24,585 ...

The L&YR had little use for such a powerful passenger locomotive, but the 2-10-0 was of great interest. The 2-10-0 was of conventional layout, with the two rear driving axles set beneath the firebox grate and ashpan. The pacific though, with the same boiler, required its higher axles to be placed ahead of the firebox.
The sixty built in 1894 and early 1895 had 17 + 1 ⁄ 2 inches (440 mm) bore, like the 2-4-2s of the same period, and the next sixty of mid-1895 to early 1896 returned to the original size. All 280 had unbalanced D slide valves. From September 1896, locomotives built with saturated boilers had 18-inch cylinders and Richardson balanced slide valves.
