The Comet class were 12 4-4-0 saddle tank broad gauge locomotives operated on the South Devon Railway and associated railways. They were designed for passenger trains on this steep and sharply curved line but were also used on goods trains when required.
Built by the Haigh Foundry. On 13 September 1866, Falcon was working the mail train when it failed to stop at the signal at Plympton so it collided with Brutus, which ran away to Plymouth. It was named after a bird, the falcon.
Ixion (1853 – 1878) GWR no. 2105
Built by Stothert and Slaughter. On 1 August 1853, Ixion was working a goods train from Exeter to Plymouth. At Rattery the driver ignored a danger signal and collided with a mail train while shunting. Ixion was badly damaged and was out of use for many months, despite having seen less than five months' work at the time. Named after Ixion from Greek mythology.
Lance (1851 – 1873)
Built by Longridge and Company. Lance was written off after it was involved in a head-on collision with another train near Menheniot railway station on the Cornwall Railway on 2 December 1873. At the time it was providing front-end assistance to a heavy goods train. The name Lance means a projectile, and was reused on a Leopard class locomotive built in 1875.
Meteor (1851 – 1881) GWR no. 2098
Built by Longridge and Company, Meteor was named after a heavenly body, a meteor.
Orion (1853 – 1878) GWR no. 2103

Osiris (1853 – 1873)
Built by Stothert and Slaughter. On 31 October 1853, it was approaching Totnes railway station with a passenger train when it was hit by a goods train which had been unable to stop after descending the incline from Rattery. After withdrawal, Osiris was taken to Portreath where it provided steam for the stationary engine that powered the cable railway which raised wagons from the harbour up to the West Cornwall Railway line.
