The Great Western Railway Leo Class 2-4-0 was a class of broad gauge steam locomotives for goods train work. This class was introduced into service between January 1841 and July 1842, and withdrawn between September 1864 and June 1874.

These locomotives were the first for the railway with coupled wheels as they were designed as goods locomotives, but they later found use on passenger trains too. All the class were altered to 2-4-0ST saddle tanks.

The locomotives were built by three different workshops, each with its own naming convention. The first three came from R and W Hawthorn and Company, who named them after strong animals. The next three were named after volcanoes by Fenton, Murray and Jackson, while the final twelve came from Rothwell and Company carrying the names of the twelve houses of the zodiac.

Notes

  1. Hecla: On 24 December 1841 it was involved in a fatal accident in Sonning Cutting near Reading. It was hauling a so-called "baggage train" consisting of both passenger and goods trucks, when it ran into an earth slip in the cutting, killing eight passengers. At the coroner's inquest on the passengers killed the jury returned a verdict of accidental death in all cases and a deodand of one thousand pounds on the engine, tender and carriages. The deodand was later overturned.
  2. Taurus: worked the first South Devon Railway train from Newton to Torquay on 18 December 1848.
  3. Sagittarius: worked the first train to Warminster on 9 September 1851.
  4. Capricorn: Along with Pisces, worked the first train from Totnes to Laira, the temporary terminus of the South Devon Railway at Plymouth on 5 May 1848.
  5. Pisces:Along with Capricornus, worked the first train from Totnes to Laira, the temporary terminus of the South Devon Railway at Plymouth on 5 May 1848.
