last two in Indian broad gauge. The GWR gave a repeat order in 1906 for a further 12 slightly more powerful units. The Mauritius Government Railways ordered one in 1907. The largest rail motor order was for 15 from the Italian State Railways. See also Kerr Stuart steam railmotor (one-off, built 1912, for Victorian Railways) 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 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 gauge lines including a 4-6-2T version for the Londonderry and Lough Swilly Railway. For Chile a very large gauge double six-coupled bogie Meyer followed in 1904 by five American style bar-framed 2-8-0 tender engines for the gauge Interocianic and Mexican Eastern Railways. In May 1910 they built a 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 19 April 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 8 June 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 gauge Gwalior Light Railway in India, the company received several orders for locomotives and a wide variety
