Locomotive and Tender, Atlantic Type, C&NW 1015, 1900

Chicago and North Western Railway 1015, 1900
Model: 323,720
This is a model of the Chicago and North Western Railway No. 1015, a high-speed passenger locomotive built by the Schenectady Locomotive Works in 1900. This model is part of the collection displayed in the museum’s Railroad Hall exhibit of 1964-2002 to illustrate the technological development of the locomotive.
On the Chicago and North Western, the 1015 and its ninety sisters pulled first class express trains of nine to eleven wooden coaches. When heavier steel cars were introduced around 1915, these engines were found wanting in power, and they were assigned to lighter, secondary trains. The last of these machines was retired in 1954. Today, the 1015 is on display at the Museum of Transportation in St. Louis, MO.
Steam locomotives are often classified by wheel arrangement, in the order of leading, driving, and trailing wheels. This engine has four leading wheels, four driving wheels, and two trailing wheels. It is therefore classified as a 4-4-2 locomotive, also known as the Atlantic type. Compared to the 2-4-2 type, like Baldwin’s Columbia, the four-wheel lead truck of the 4-4-2 improved stability. To generate the heat needed to boil water, steam locomotives burn fuel in a chamber called the firebox. As of 1900, most fireboxes were fitted between the two rear driving wheel axles, a practice that limited firebox size. The resulting steaming capacity of even the largest 4-4-0 type engines, like the New York Central’s No. 999, limited them to only occasional bursts of high speed. On the 4-4-2 Atlantic type, however, a large firebox was fitted behind the rear axle and supported by the pair of trailing wheels. The larger firebox generated the steam needed to haul heavy passenger trains at sustained high speeds. For this reason, the 4-4-2 soon superseded the 4-4-0 American type on premier passenger runs.
The Atlantic type was built in 1900 by Schenectady Locomotive Works, and was a passenger locomotive made to haul nine wooden coaches (400 tons) at 70-80 miles per hour. The No. 1015 was acquired by the St. Louis National Museum of Transport around 1948. At least one “D” class locomotive was in service as late as 1953.
