Midland Railway Class 2 4-4-0 : ウィキペディア英語版 | Midland Railway Class 2 4-4-0 The Midland Railway Class 2 4-4-0 was a series of 12 classes of 4-4-0 steam locomotives built by and for the Midland Railway between 1876 and 1901 while Samuel W. Johnson held the post of locomotive superintendent. They were designed for use on express passenger trains but later on were downgraded to secondary work when more powerful types were introduced. During their history they were repeatably rebuilt, sometimes leaving virtually none of their original parts. ==As built== 275 were built in all: The "B", "D" and "E" boilers all had the same 4 ft 1 in diameter barrel, but had progressively longer fireboxes, "D" 7 inches longer than "B" and "E" 6 inches longer than "D", giving a larger grate area. Starting with the "1738" class boilers were made of steel rather than wrought iron, which accounts for the higher permitted pressures.
