Before his big rail breakthrough in 1804, British mining engineer, inventor and explorer Richard Trevithick had been working on high-pressure steam engines for several years with mixed results, from the successful demonstration of the 'Puffing Devil' steam-powered road locomotive in 1802 to disaster in …
The efficiency of the diesel locomotive is 34.6% while for the SOFC is 47.6%, and it is more cost effective. Andrew et al. (2012) studied the feasibility of the SOFC with gas turbine hybrid long-haul freight locomotive. The study used the diesel reformat and compared with the natural gas reformat and the hydrogen as fuel.
Steam locomotives dropped their fires for last time in everyday use in China in mid-January with the end of operations at a coal mine in Xinjiang Province, ending three decades during which the country became famous with railfans worldwide as the last refuge of steam operation. New steam locomotives were still being built in the late 1990s.
