Predominantly it was the Iron works in Dowlais, Plymouth (in lower Merthyr) , Cyfarthfa and Penydarren
The first train, called the Penydarren, was built in 1804 by Richard Trevithick. At that time, trains were known as locomotives.
In 1804, Richard Trevithick built the first steam locomotive railway, Penydarren, to haul iron ore from Merthyr Tydfil to Abercynon, Wales.
Richard Trevithic in 1801 Cornwal. His first running model on lines was in 1802 , Penydarren, Merthyr Tydfil South Wales
In 1804, invented by Richard Trevithick, the worlds first full scale locomotive pulled a train along the tramway of the Penydarren Ironworks, Merthyr Tydfil, Wales.
The first attempts were made in Great Britain; the earliest steam rail locomotive was built in 1804 by Richard Trevithick and Andrew Vivian. It ran with mixed success on the narrow gauge "Penydarren tramroad" at Merthyr Tydfil in Wales.
The first full scale working railway steam locomotive was built in the United Kingdom in 1804 by a gentleman called Richard Trevithick. He was an English engineer born in Cornwall. This used high pressure steam to drive the engine by one power stroke. (The transmission system employed a large flywheel to even out the action of the piston rod.) On 21 February 1804 the world's first railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil in South Wales (UK). There is a memorial in the image of that locomotive in the town at a area between Penydarren and the top of the Merthyr Town area called Pont Morlais that celebrates this event
That would possibly be a British 2004 Two Pound coin depicting Trevithick's Penydarren locomotive. These coins are still potentially in circulation so, unless they are part of a Proof or Uncirculated mint set or are individual Proof or Uncirculated coins and in absolute mint condition, they are worth Two Pounds.
