William Cook Rail, a World Class CompanyWilliam Cook Rail is a world-leading authority in the design, development, manufacture and overhaul of passenger bogie components and complete coupler systems.
It is part of the William Cook group, a British engineering conglomerate with 500 employees across three factories in Sheffield, Leeds and County Durham that can trace its history to 1840.
William Cook has recently invested £15 million in state-of-the-art machine tools and other equipment, including an industrial 3D printing suite, to enable manufacture of full-size prototypes to the same specification as production parts. These prototypes can then be used by train builders for safety testing of components before a design is finalised.
William Cook uses its own high-energy radiography to confirm the integrity of all products. Laser scanning, MPI and UT complete the William Cook range of testing facilities. The group is certified to ISO9001, ISO14001, OHSAS 18001, EN15085 (welding for railway vehicles and components), RISAS and is currently under certification for IRIS.
