While Richard Trevithick managed to build his first steam locomotive in 1804, lack of marketing and the will to continue innovating enabled other inventors to step in and try their luck. In early 1800s he started working in a mine that had one of the early examples of stationary steam machines built by James Watt.
In 1698, Thomas Savery, an English inventor, patented a device that allowed for the use of steam to pump water. The steam engine that he created was used to remove water from mines. This design was improved upon by English engineer Thomas Newcomen in 1712.he steam powered engine is the heart of the steam locomotive. In order to understand how the locomotive works, it is important to first understand how the steam engine operates. This involves water and fire, which is used to create heat.
