simple expansion (simplex) locomotives included Nigel Gresley's LNER Class D49 Hunt and Shire 4-4-0s of 1927–28. However, the most powerful and one of the most successful 4-4-0 designs ever constructed was the Schools class of the Southern Railway, designed by Richard Maunsell and built between 1930 and 1935. These were used on secondary express trains between London and South Coast towns, until their withdrawal in 1962. United States Since the first locomotives in the United States were imported from the United Kingdom, the British was also adopted by the first United States railroads. When new locomotive construction began in the United States in 1831, some new railroads opted for a different gauge, resulting in breaks-of-gauge as railroads began to be joined. Apart from freight reloading issues, another result was that new locomotives for some of these railroads had to be delivered on flatcars. The 4-4-0 played a major role in the development of rail transport in the United States. Some of the notable 4-4-0 locomotives that saw service on United States railroads are: The General, built in 1855 by Rogers, Ketchum & Grosvenor in Paterson, New Jersey, was the fleeing locomotive during the Great Locomotive Chase of the American Civil War. The Texas, built in 1856 by Danforth, Cooke & Company in Paterson, New Jersey, was the pursuing locomotive during much of the Great Locomotive Chase. The Jupiter, Central Pacific Railroad’s No. 60, built by Schenectady Locomotive Works of New York in September 1868, was one of the two locomotives to meet at Promontory Summit during the Golden Spike ceremony upon the completion of the First American Transcontinental Railroad on May 10, 1869. Union Pacific No. 119, built by Rogers Locomotive & Machine Works of Paterson, New Jersey in 1868, was the other locomotive at Promontory Summit on May 10, 1869. The Virginia & Truckee Railroad’s Dayton, built in 1873 by the Central Pacific Railroad, had the honor of opening the branch line between Carson City and Minden in Nevada in 1906. The New York Central and Hudson River Railroad no. 999, built in 1893 to haul the railroad's Empire State Express, is believed to have been the first in the United States to travel at a speed of more than . Walt Disney World Railroad No. 4 Roy O. Disney was built in February 1916 by the Baldwin Locomotive Works, originally as No. 66 (later No. 251 in the
