The Banking Class were five 0-6-0ST broad gauge steam locomotives for assisting ("banking") trains up inclines on the Great Western Railway. Designed by Daniel Gooch, they were tank engine versions of his Standard Goods class, and mainly built at Swindon Works.
The last one was withdrawn in 1889.
- Avalanche was not part of the Swindon-built Standard Goods locomotive build, but instead it was built by the Stothert and Slaughter and was similar to the Caesar class tender goods engines.
- The name Avalanche comes from a snow slip.
- Bithon (1854 - 1871)
- Iago (1852 - 1881)
- Iago was a character in William Shakespeare's Othello.
- Juno was sold to the South Devon Railway in June 1872, where it was renamed Stromboli. It returned to the GWR upon absorption of the SDR in 1876, when it was given the number 2138 but retained its Stromboli name. It was the last survivor, being withdrawn in June 1889.
- Juno was a Roman goddess; Stromboli is an Italian volcano.
- Plato was a Greek philosopher.
