GWR Charles Tayleur locomotives

The first 19 locomotives ordered by Isambard Kingdom Brunel for the Great Western Railway included six 2-2-2 Charles Tayleur locomotives. They were built by Charles Tayleur at his Vulcan Foundry but were unsuccessful and rapidly supplemented by the Star Class locomotives ordered by Daniel Gooch once he had been appointed as the Locomotive Engineer.

• Vulcan (Tayleur 51; 1837–1868)

This locomotive was the first to run on the Great Western Railway when it was tested on 28 December 1837 from its shed at West Drayton. It was withdrawn in 1843 but was rebuilt as a 2-2-2T tank locomotive and returned to service in 1846, running in this form until 1868. It survived for two more years at Reading as a stationary boiler. Although named after the workshops where it was built, Vulcan is also the Roman god of fire.

• Æolus (Tayleur 52; 1837–1867)

This locomotive worked the first train on the Great Western Railway when it opened on 4 June 1838. In 1843 it was fitted with more conventional 6-foot-0-inch (1.83 m) driving and 3-foot-0-inch (0.91 m) carrying wheels with 15-by-18-inch (380 mm × 460 mm) cylinders; at some time it was converted to a 2-2-2T tank locomotive. The name Æolus is quite common in Greek mythology, shared by at least three mythic characters.

• Bacchus (Tayleur 53; 1837–1842)

This locomotive was named after Bacchus, the Roman god of the harvest and was later carried by a Pyracmon Class goods locomotive.

• Apollo (Tayleur 62; 1838–1867)

This locomotive was rebuilt in 1839 with new cylinders 15 by 18 inches (380 mm × 460 mm) and was altered to become a 2-2-2T before it ceased work in 1867. It was named after the important Greek god, Apollo.

Neptune is the Roman god of the sea. The name was later carried by one of the Ariadne Class standard goods locomotives.

• Venus (Tayleur 64; 1838–1870)

This locomotive was withdrawn in 1843 but was rebuilt and returned to service in 1846. It now had 6-foot-0-inch (1.829 m) driving and 3-foot-0-inch (0.914 m) carrying wheels, with 15-by-18-inch (381 mm × 457 mm) cylinders; at some time it was also converted to run as a 2-2-2T tank locomotive. The name, which represents the Roman goddess of love, was also carried by a Fire Fly Class locomotive from 1841.
