The Great Western Railway (GWR) Star Class of 2-2-2 broad gauge steam locomotives were used for passenger train work. Designed by Robert Stephenson, the class was introduced into service between November 1838 and November 1841, and withdrawn between April 1864 and September 1871. A total of twelve Star Class locomotives were manufactured. Notably, they were given the romantic or colloquial (rather than scientific) names of astronomical bodies. By the time the last had been delivered, GWR engineer Daniel Gooch had designed and taken delivery of several of his larger Firefly Class. North Star and Morning Star North Star (1837–1871) North Star arrived at Maidenhead Bridge station by barge on 28 November 1837; on 31 May 1838 it worked the inaugural train for the company's directors. In 1854 it was rebuilt with cylinders and the wheelbase lengthened by . It was withdrawn in 1871 but kept at Swindon, along with Lord of the Isles, until 1906. It was then dismantled but many parts were recovered to build the later replica. 'The north star' is one of two common alternative names for Polaris (its other being 'the pole star'). It is the only visible polar star in either hemisphere, and has long been used for navigation due to its constant fixed and unmoving appearance due north in the night sky. The commercial park north of Swindon Station is called North Star after the engine and includes streets named North Star Avenue and Polaris Way. Morning Star (1839–1869) This, the second Star Class, was not delivered until 14 months after the North Star. It had smaller wheels, as had been intended when it was constructed for the New Orleans Railway; the wheelbase was . Named after 'the morning star', the common periodic name for the planet Venus (at times the brightest object in the night sky) when seen in the eastern sky just before sunrise, its motion then appearing to "lead" the sun for many mornings. Later locomotives Bright Star (1841–1864) A 'bright star' is one clearly visible in the night sky, and generally denotes one of a few that appear to shine more than most. Dog Star (1839–1869) After withdrawal, Dog Star was used as a stationary boiler at Paddington. Named after 'the dog star', the common name for Sirius, brightest star in the night sky and found in the constellation Canis Major (Lat: 'greater dog', from whence Sirius' common name). Evening
