Richard Trevithick from Camborne in Cornwall was carrying out work on the stationary steam engines at the Penydarren Iron Works for Samuel Homfrey. For some time he had been experimenting on self-propelled steam vehicles. Whilst at Penydarren, he had the opportunity to try his railway locomotive on the Penydarren Tramroad.

On 21st February, 1804, Richard Trevithick’s locomotive was used to haul a train of 10 tons of iron and 70 passengers along the Penydarren Tramroad from Merthyr to Abercynon (then known as Navigation), a distance of nearly ten miles. This was the first steam engine to haul a load on rails!
