History: The Heavy Mikado was "conceived" under the auspices of the United States Railway Administration (USRA), an agency established during WWI to regulate the railroad industry during the war. One of the first undertakings of the USRA was to develop locomotive (and rolling stock) designs that the railroads could share. This "common design" program was highly successful in streamlining production, and many USRA engines were used long after the war was over, essentially "outliving" the agency that conceived them.
The 2-8-2 is a railroad steam locomotive that has one leading axle followed by four powered driving axles and one trailing axle. This configuration of steam locomotive is most often referred to as a Mikado, or shortened to just "Mike". The USRA ultimately created 12 different steam locomotive designs, including both the Heavy Mikado and Light Mikado. Both the Light and Heavy Mikado used the same 63" drivers and running gear, but the Heavy Mike had a fatter boiler and put out more pounds on the drivers. This resulted in a more powerful locomotive.
Under the USRA's watch, 233 Heavy Mikados were built. Including copies built later, the total number of Heavy Mikes was 957 units, purchased originally by 23 different railroads, primarily in freight service. Some Mikado steam engine are still in service today, employed mostly for tourist or railfan trips.
On April 6th, 1917, the United States entered World War I, and very soon the nation's railroads proved inadequate to the task of serving the war effort. There were several sources of the problem. Although the carriers had made massive investments in the first years of the 20th century, there remained inadequacies in terminals, trackage, and rolling stock. Inflation struck the American economy, and when in 1906 Congress empowered the Interstate Commerce Commission (ICC) to set maximum shipping rates, the rail firms had difficulty securing revenue sufficient to keep pace with rising costs. The ICC did allow some increases in rates, however. Also, investors had overexpanded the nation's trackage, so by late 1915 fully one-sixth of the railroad trackage in the country belonged to roads in receivership (bankruptcy). The railroad unions (commonly called "brotherhoods"), desiring shorter working days and better pay, threatened strike action in the second half of 1916. To avert a strike, President Woodrow Wilson secured Congressional passage of the Adamson Act, which set the eight-hour work day as the industry standard. When the Supreme Court ruled the law constitutional, the carriers had no choice but to comply.
Over 100,000 railroad cars and 1,930 steam locomotives were ordered by the USRA at a cost of $380 million, all of new USRA standard designs, which were up-to-date and standardized types, designed to be the best that could be produced to replace outdated equipment.
