We just learned about the Salamanca steam locomotive.
Another famous steam locomotive was called Locomotion No. 1, made by George and Robert Stephenson in 1825 in England.
This was the first steam locomotive that was used to bring people along in passenger cars.
The first time this locomotive was put to the test it hauled 11 wagons of coal, and special passenger carriage, and then 20 more wagons that were filled with people.
The train could go about 12 miles per hour, and it took the people on a 10 mile trip from Shildon to Darlington.
