The [[Great Western Railway]] (GWR) '''Ariadne Class''' and '''Caliph Class''' were [[broad gauge]]  [[0-6-0]] [[steam locomotive]]s designed for goods train work by [[Daniel Gooch]] and are often referred to as his '''Standard Goods''' locomotives.

The class was introduced into service between May 1852 and March 1863, and were built in seven lots at [[Swindon Works|Swindon]] with a total of 102 locomotives.{{sfn|Reed|1953|p=B24}} All were withdrawn between 1871 and 1883 except for ''Europa'', which was extensively rebuilt in 1869 and survived until the end of the GWR broad gauge in May 1892.
