Atchison, Topeka & Santa Fe Mikados

The first "Mikados" on the Atchison, Topeka & Santa Fe Railway came from the Baldwin Locomotive Works in 1902 and 1903. They were assigned road numbers 885 - 899. These 2-8-2s were Vauclain compounds with a wide firebox, which extended over the rear wheels. They were converted to simple expansion locomotives in 1908 and saw service for the next four decades. In 1913, the next group of "Mikados" was purchased from Baldwin. This group was assigned road numbers 3100 - 3128. They had the same basic design as the converted locomotives of 1908.

More 2-8-2s arrived in 1916, when Baldwin delivered a group of thirty, which were given road numbers 3129 - 3158.

Between 1917 and 1920, the AT&SF received a total of 128 more "Mikados". This group, assigned road numbers 3160 - 3287, were significantly heavier than the earlier ones. The last group of new 2-8-2s to be added to the roster was a group of 101 built by Baldwin between 1921 and 1926. This group, road numbers 4000-4100, had the same specifications as the 3160-3287 locomotives.

There were five other "Mikados" on the roster. They were two AT&SF shop-built and three second-hand locomotives bought from the PRR. The San Bernardino shops took apart two 2-8-8-2s (numbers 1798 and 1799) and used the rear engines to build two 2-8-2s. These two locomotive were completed in 1924 and carried the same road numbers as the 2-8-8-2s. The three from the PRR came in 1945 and were ex PRR numbers 4031 built by Baldwin in 1917, number 4185 built by the PRR in 1917 and number 7342 built by Baldwin in 1917.

There are two surviving AT&SF 2-8-2 "Mikado" type locomotives. However, these two locomotives (numbers 3167 and 4076) were lost in a flood in 1952 and are now sunk in the Kaw River in Topeka, KS.
