James 
                                        Watt, a Scottish inventor and mechanical 
                                        engineer, was responsible for improvements 
                                        to the steam engine that caused this device 
                                        to see wider use and encouraged wider 
                                        experimentation, though it was not used 
                                        for locomotive power until Richard Trevithick 
                                        developed the high pressure steam engine 
                                        in the 1800s. The first steam locomotive 
                                        was built by Richard Trevithick, an English 
                                        engineer, in 1804. His locomotive had 
                                        no name, and was used at the Pennydarren 
                                        ironworks in Wales. It was not financially 
                                        successful, because it was too heavy for 
                                        the track and kept breaking down. Despite 
                                        his inventive talents, Richard Trevithick 
                                        died in poverty, with his achievement 
                                        being largely unrecognized. In 1812 Oliver 
                                        Evans, a United States engineer and inventor, 
                                        published his vision of what steam railways 
                                        could become,
                                        
                                        
                                        
                                        
                                        
                                        
                                        with 
                                        cities and towns linked by a network of 
                                        long distance railways plied by speedy 
                                        locomotives, greatly reducing the time 
                                        required for personal travel and for transport 
                                        of goods. Evans specified that there should 
                                        be separate sets of parallel tracks for 
                                        trains going in different directions. 
                                        In 1813, George Stephenson persuaded the 
                                        manager of the colliery where he worked 
                                        to allow him to build a steam-powered 
                                        machine. He built the Blucher, the first 
                                        successful flanged-wheel adhesion locomotive. 
                                        The flanges enabled the trains to run 
                                        on top of the rails instead of in sunken 
                                        tracks. This greatly simplified construction 
                                        of switches and rails, and opened the 
                                        way to the modern railroad.
