The first steam locomotive was developed in the UK in 1804 by Richard Trevithick. The first trial run happened on February 21, 1804 in South Wales. It was a 9 mile run with a top speed of 5 mph. There are no known pictures of the original engine. All the information about the engine is found in a partial blueprint , personal letters and word of mouth. There are a number of replicas of the original engine based on a conscientious of information at the time. My model is based on research of this information. I will post pictures of my project as it is built. The first two images below are sketches and pictures of replicas of the first oribinal engine.

I have the fire box completed. The piston with rings along with the piston rod packing glan is completed. I have the cross head just about complete. I did a trial run of the engine on compressed air and it was successful. In a week or two I should have the boiler buttoned up and will run a complete test of the boiler and engine as a unit.
