Lake Erie is the fourth - largest lake ( by surface area ) of the five Great Lakes in North America , and the thirteenth - largest globally if measured in terms of surface area . It is the southernmost , shallowest , and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time . At its deepest point Lake Erie is deep . Lake Erie ' s northern shore is bounded by the Canadian province of ___MASK22___ , with the U . S . states of Ohio , Pennsylvania , and New York on its southern and easternmost shores and Michigan on the west . These jurisdictions divide the surface area of the lake by water boundaries .

Richard Trevithick ( 13 April 1771  22 April 1833 ) was a British inventor and mining engineer from Cornwall , England . The son of a mining captain , and born in the mining heartland of Cornwall , Trevithick was immersed in mining and engineering from an early age . He performed poorly in school , but went on to be an early pioneer of steam - powered road and rail transport . His most significant contribution was the development of the first high - pressure steam engine . He also built the first full - scale working railway steam locomotive . On 21 February 1804 the world ' s first locomotive - hauled railway journey took place as Trevithick ' s unnamed steam locomotive hauled a ___MASK3___ along the tramway of the Penydarren Ironworks , in Merthyr Tydfil , Wales . A steam locomotive is a railway locomotive that produces its pulling power through a steam engine . These locomotives are fueled by burning combustible material  usually coal / coke , wood , or oil  to produce steam in a boiler . The steam moves reciprocating pistons which are mechanically connected to the locomotive ' s main wheels ( drivers ). Both fuel and water supplies are carried with the locomotive , either on the locomotive itself or in wagons ( tenders ) pulled behind . The first steam locomotive , made by Richard Trevithick , first operated on 21 February 1804 , three years after the road locomotive he made in 1801 . The first practical steam locomotive was built in 1812 - 13 by John Blenkinsop . The ___MASK89___ was an American Class I railroad , founded in 1846 .

The engine is currently owned by the Railroaders Memorial Museum in Altoona , Pennsylvania . It is one of the only two remaining K4s locomotives and , along with PRR 3750 , was designated the official state steam locomotive in 1987 by the Pennsylvania General Assembly . ___MASK74___ is a large railroad industrial complex in Altoona , Pennsylvania . It was built by the Pennsylvania Railroad ( PRR ) to supply the railroad with locomotives , railroad cars and related equipment . For many years it was the largest railroad shop complex in the world .
