    Numbering 30 locomotives, the 2900-class Northerns were the road's last newly
    purchased, steam-powered passenger engines. Manufactured by Baldwin during
    the War-years, these "Big Mountains", as the wheel configuration was once called
    by the Santa Fe, were the product of wartime materials shortages, especially high-
    strength alloys. Being forced to defer to heavier, lower tensile-strength components
    to maintain the necessary overall strength, they were about 8-tons heavier than the
    similar 3776-class. They weighed just over 510,000 pounds, not including the
    tender, and had the distinction of being the heaviest 4-8-4s ever built.

    The 2900s were built with 80" Baldwin-licensed Boxpok drivers, made at its
    Standard Steel Works (SSW) foundry. Later, the #4 axle, on most locomotives of the
    class, was replaced with Baldwin discs along with other post-War modifications,
    including lightweight roller bearing rods, and telescoping stack extensions. The
    substitution of the Baldwin disc driver was apparently an effort to improve engine
    balance and the riding qualities of these locomotives.

    Six examples of these fine locomotives are preserved; however, had more diesels
    been available, the 2900s may have never left the drawing boards at Topeka.
