Walter Alexander Coachbuilders^[1] was a Scottish builder of bus and coach bodywork based in Falkirk. The company was formed in 1947 to continue the coachbuilding activities of W. Alexander & Sons when their bus service operation was nationalised. After several mergers and changes of ownership it now forms part of Alexander Dennis.

In 1913, Walter Alexander founded Alexander's Motor Service to expand upon the Falkirk & District Tramways Company's route into previously unserved Grangemouth.^[2]

In 1924, believing in the future of the omnibus, Alexander established W. Alexander & Sons Limited, to run them and to manufacture bodywork for its own fleet and for sale to other operators.^[3][2] In 1928, several of the major British railway companies bought into the Scottish Motor Traction Company (SMT). Walter Alexander decided to sell his business to the SMT group in 1929, and through this action, received access to a vast supply of resources and services. Alexander became an in-house supplier of bodywork for the whole of the SMT group, and only a few bodies were built for other customers during this period.^[3]

Coachbuilding work had initially taken place at the company's main bus garage and works in Brown Street, Camelon, but it outgrew this facility and in 1930 a bus garage in Drip Road, Stirling was converted into a dedicated coachbuilding factory,^[3] although a few bodies for Alexander's own fleet did continue to be built at Brown Street in the 1930s and '40s.

In 1947, in anticipation of the newly elected Labour Government's nationalisation of the SMT group's bus services, a new company, Walter Alexander & Company (Coachbuilders) Limited^[1] was formed in order to keep the coachbuilding business in private hands.^[4] Although Alexander remained the largest supplier of bodywork to what became the Scottish Bus Group, the independent company also began to broaden its customer base. The company outgrew the Drip Road premises and in 1958 it relocated to a purpose-built factory at Glasgow Road, Camelon.

The coachbuilding business continued to flourish and expansion was rapid. In 1969, the company bought out Potters, a bodybuilder in Northern Ireland, and set up a subsidiary Walter Alexander & Co (Belfast) Limited,^[2][5] and within six years started selling buses to the Far East. In 1981 the company was awarded the Queen's Award for Export.^[6] By 1983, the company was the largest supplier of double-deck bus bodies in the world,^[7] and a year later it won a British Rail contract to construct 25 Class 143 carriages.^[8] In 1987, Walter Alexander became a publicly listed company, having previously been a private firm run by the Alexander family.^[9]

The ownership of the company subsequently changed several times: In 1990 the family sold the company to Spotlaunch plc but within two years a management buyout occurred and it became a standalone company until 1995, when it was bought by the Mayflower Corporation plc.^[10][11][12] In 2001, it was incorporated into TransBus International. It is now part of Alexander Dennis.^[13]

Walter Alexander built many different types of bodywork over 50 years, with the most famous being the Y-Type single decker.
