The first modern steam engine was developed by James Watt (1736-1819), a Scottish engineer, in the 1760s. Building from the earlier steam engine developed by Thomas Newcomen, Watt made several significant improvements to his predecessor's model. Watt's key enhancement was a separate condenser which helped to solve the massive heat loss and resulting inefficiency which characterized Newcomen's model. In Watt's model, a cylinder head forced the piston down in a partial vacuum by means of steam. Watt finished his model in 1765, and the first steam engine of Watt's design came out in 1769, the same year Watt's idea was patented. Watt took some of his ideas from another inventor and engineer named Humphrey Gainsborough (1718-1776).
He didn't. The steam engine was invented by James Watt in 1712. Trevithick developed an improved high pressure steam engine in 1800. He then invented the steam locomotive in 1803 and actually built a passenger railway in London in 1812. Thomas Newcomen gave his name to atmospheric steam engines, which he invented. The first was installed in 1712 close to Dudley Castle in the Black Country. He had to share his success with Thomas Savery, who had previously taken out a general patent covering all the possible means of pumping water by ateam power.
