context_page_description: Sans Pareil is a steam locomotive built by Timothy Hackworth which took part in the 1829 Rainhill Trials on the Liverpool and Manchester Railway, held to select a builder of locomotives. The name is French and means 'peerless' or 'without equal'.
  While a capable locomotive for the day, its technology was somewhat antiquated compared to George and Robert Stephenson's Rocket, the winner of the Rainhill Trials and the £500 prize money. Instead of the fire tube boiler of Rocket, Sans Pareil had a double return flue. To increase the heating surface area, the two flues were joined by a U shaped tube at the forward end of the boiler; the firebox and chimney were both positioned at the rear same end, one on either side.
  Sans Pareil had two cylinders, mounted vertically at the opposite end to the chimney, and driving one pair of driving wheels directly - the other pair were driven via connecting rods, in the typical steam locomotive fashion.
  At the Rainhill Trials, Sans Pareil was excluded from the prize because it was slightly over the maximum permitted weight. Nevertheless, it performed very well but had a strange rolling gait due to its vertical cylinders.
context_section_description: A replica locomotive, built in 1980, is now preserved by the National Railway Museum at its new Shildon Locomotion Museum annex, which is also home to what remains of the original locomotive.
