London Steam Carriage
early steam-powered road vehicle
The London Steam Carriage was an early steam-powered road vehicle constructed by Richard Trevithick in 1803 and the world's first self-propelled passenger-carrying vehicle. Cugnot had built a steam vehicle 30 years previously, but that had been a slow-moving artillery tractor, not built to carry passengers.
History
In 1801, after James Watt's earlier patent on "a carriage propelled by a steam engine" had expired, Richard Trevithick constructed an experimental steam-driven vehicle (Puffing Devil) at Camborne, Cornwall. It was equipped with a firebox enclosed within the boiler, with one vertical cylinder, the motion of the single piston was transmitted directly to the driving wheels by means of connecting rods. It was reported as weighing 1,520 kg (3,350 lb) fully loaded, with a speed of 14.5 km/h (9 mph) on the flat. Trevithick ran this for several hundred yards up a hill with several people hanging on to it. Unfortunately, while the driver and passengers were in a pub celebrating the event, it set fire to a shed in which it had been left unattended, and was destroyed.
The following year, Trevithick and his partner, his cousin Andrew Vivian, patented a steam coach, the patent also describing other uses for Trevithick's new high-pressure engines. The vehicle was assembled at Felton's carriage works at Leather Lane, London, the engine components having been brought from Falmouth where they were made.
In 1831, Trevithick gave evidence to a Parliamentary select committee on steam carriages.

Why this record matters
“London Steam Carriage” is worth following because a concise public description often conceals a longer documentary argument. Here, London, Steam and Carriage provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 12, 2025. The linked authority identifier is Q6670814. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1803, 1801 and 1831.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
