The first steam engine in the world first runat 25 mph on the Mohawk & Hudson Railroad between Albany and Schenectady
The first person to harness the power of steam was the Greek scientist Heron of Alexandria in the first century A.D. He developed several devices that were operated by water, steam, or compressed air, including a fountain, a fire engine, and the steam engine. The steam engine was significantly improved in 1711 by Englishman Thomas Newcomen (1663-1729), who created a machine that used steam to pump water. The Scottish inventor James Watt (1736-1819) substantially improved on Newcomen's model and patented (received exclusive rights to make, use, and sell) his own steam engine in 1769.
American, Sylvester Howard Roper (1823-1896) invented a two-cylinder, steam-engine motorcycle (powered by coal) in 1867. If you allow your description of a motorcycle to include a steam engine, then Howard Roper could be considered the inventor of the motorcycle. Howard Roper also invented a steam engine car.
Many men developed the steam engine. It was a process of evolution, so that it would be difficult to pin down to two men. I would think that Newcomen, Watt, Boulton, Leupold, Smeaton and Trevithick all played parts in this.

There are no longer any class 1 railroads operating steam engine trains on a regular basis. The Union Pacific Railroad maintains two operable steam engines and they make periodic special runs, and charters. The only other steam engines in operation today are on tourist railroads, there are a number of those around the country.
Thomas is a steam driven tank engine. A tank engine is a locomotive that carries water in either one or two tanks, rather than towing a water and fuel tender.
The first ever motorbike was invented in 1885 by a two Germans Gottlieb Daimler and Wilhelm Maybach. Prior to this, in 1867, an American by name Sylvester Howard Roper invented a two-cylinder, steam-engine motorcycle which was functioning with the help of coal. he also invented a steam engine car.
