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. As built, they comprised two groups of three: the first group, delivered in 1837, had cylinders having a bore of 14 inches (360 mm) and the second group, delivered in 1838, had cylinders having a bore of 12 inches (300 mm); all had a stroke of 16 inches (410 mm).

• 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 It was withdrawn in 1843 but was rebuilt as a 2-2-2T tank locomotive and returned to service in 1846, running in this form until 1868.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. It is named after the workshops where it was built, which themselves were named after 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 (1.829 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 converted to a 2-2-2T tank locomotive.

• Bacchus (Tayleur 53; 1837–1842)

The name was later carried by a Pyracmon Class goods locomotive.
