These road experiments were the prelude to the great triumph at Penydarren , Merthyr Tydfil , in 1804 . Trevithick had been engaged as an engineer by Samuel Homfray (q.v.) , ironmaster of the Penydarren Iron-works , during the latter part of 1803 , and very soon was engaged in making a steam locomotive with the aid of the Penydarren mechanics and fitters, which they hoped to utilise on the tramway, then recently erected to convey the manufactured iron from the Penydarren , Dowlais , and Plymouth Works to the Basin or Navigation (now called Abercynon ) and so avoid the canal, then largely owned and controlled by their competitor, Richard Crawshay of Cyfarthfa (q.v.) . By 13 Feb. 1804 , the steam engine was completed, and Trevithick wrote, ‘ We put it on the tramway. It worked very well. … ’ By 20 Feb. he reported that the ‘ Tram Waggon ’ had been at work several times, and that it worked ‘ very well, and is much more manageable than horses .’ This was the day before the advertised day of the great experiment which attracted an immense crowd of spectators. At Merthyr , on 19 March 1934 , was unveiled a monument raised to his memory by the Trevithick Centenary Commemoration Committee . He d. 22 April 1833 at Dartford .
