OO gauge or OO scale is the most popular standard gauge model railway standard in the United Kingdom, outside of which it is virtually unknown. OO gauge is one of several 4 mm-scale standards, and the only one to be marketed by major manufacturers. The OO track gauge of 16.5 mm corresponds to prototypical gauge of 4 ft 1+1⁄2 in, rather than 4 ft 8+1⁄2 in standard gauge. However, since the 1960s, other gauges in the same scale have arisen—18.2 mm (EM) and 18.83 mm (Scalefour)—to reflect the desire of some modellers for greater scale accuracy.

Hornby Hobbies Limited is a British-owned scale model manufacturing company which has been focused on model railways. Its roots date back to 1901 in Liverpool, when founder Frank Hornby received a patent for his Meccano construction toy. The first clockwork train was produced in 1920. In 1938, Hornby launched its first OO gauge train. In 1964, Hornby and Meccano were bought by their competitor, Tri-ang Railways, and sold when Tri-ang went into receivership. Hornby Railways became independent again in the 1980s, and became listed on the London Stock Exchange, but due to financial troubles reported in June 2017, became majority owned by British turnaround specialist Phoenix Asset Management.
