Richard Trevithick of Cornwall had experimented with various models of steam locomotive, and in 1805 his work had culminated in an engine for the Wylam Colliery.
•
The Murray/Blenkinsop locomotives had the first double-acting cylinders and, unlike the Trevithick pattern, no flywheel.
•
Two locomotives of this pattern were also made by the Royal Iron Foundry in Berlin.
•
In the early nineteenth century, attempts were being made to employ steam power for haulage.
