Custom-built Designs

In addition to the company's standard designs the company accepted many orders to build to the customers' own designs in all gauges. The most impressive example for this certainly are the legendary 0-4-0LB locobreaks from 1900, strong and heavy tank engines designed to secure the trains through a cable claw on SPR (São Paulo Railway) and later EFSJ (Estrada de Ferro Santos a Jundiaí)'s 5 ft 3 in (1,600 mm) gauge mountain cable incline between Paranapiacaba and Piaçagüera. Six of them are preserved.

An example of a narrow-gauge 0-4-0 tank engine, number 652 built in 1899, worked in the docks at Walvis Bay, Namibia, until the 1950s and is now preserved in a purpose-built glass-windowed display hut in the forecourt of Walvis Bay station.

The California works produced in 1903/4 a 4-6-0 design for several Irish 3 ft (914 mm) gauge lines including a 4-6-2T version for the Londonderry and Lough Swilly Railway. For Chile a very large 3 ft 6 in (1,067 mm) gauge double six-coupled bogie Meyer followed in 1904 by five American style bar-framed 2-8-0 tender engines for the 3 ft (914 mm) gauge Interocianic and Mexican Eastern Railways. In May 1910 they built a 2 ft (610 mm) gauge "modified Fairlie" for service in Madras. This was not a Fairlie but just two 0-4-2T engines permanently coupled back to back, the only articulation being between the two complete engines. They received a repeat order for this combination.

A truly remarkable standard gauge build of 1910 was a class of four handsome 4-2-2 express passenger locomotives to the design of E. J. Dunstan for the Shanghai Nanking Railway. The order was received on April 19, 1910 and the novel design required the production of totally new drawings and patterns for all parts. Even so, the first engine was steamed just seven weeks later on June 8, 1910. In service these engines, probably the last, and the biggest, single driver engines ever built, proved to be fast (60 mph), smooth running, and very economical on fuel when compared with similar 4-4-0 engines on the same line.

From the 2 ft (610 mm) gauge Gwalior Light Railway in India, the company received several orders for locomotives and a wide variety of rolling stock over the years, culminating in the construction of four large 2-8-2 tender engines in 1928. Six very powerful superheated 4-8-0 mixed traffic locomotives built in 1929 were the last of a series of 4-4-0 and 4-6-0 machines built for the Buenos Aires Central Railway of Argentina.

In common with most British locomotive builders, in the postwar era Kerr, Stuart received a number of large orders from the mainline companies who were seeking to replace obsolete inherited equipment with their own standard designs. In 1920 the Metropolitan Railway ordered eight superheated 4-4-4 passenger tank engines for the Aylesbury service. Between 1925 and 1927 the Stoke works built fifty standard class 4F 0-6-0 goods engines for the London Midland and Scottish Railway and in 1929 and 1930 a batch of 25 GWR 5700 Class 0-6-0PTs were built for the Great Western Railway.

Famous quotes containing the word designs:

    I have no scheme about it,—no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?—and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?
    Henry David Thoreau (1817–1862)
