The Museum of Transportation, St. Louis, Missouri USA, has numerous locomotives and train cars of various types. They also have an indoor antique auto museum.
Locomotive # 1621 is a 2-10-0 Decapod type freight locomotive (ten drive wheels on axles making a five drive wheel unit) built by Baldwin Locomotive Works for Imperial Russia which contracted with Baldwin in 1915 for some 1200 locomotives. Twenty of these were purchased by the “Frisco” and changes were made to meet American standards including widening the wheel tread to accommodate the 3 1/2 gauge difference. Number 1661 has 52" drivers and weighs 362,100 pounds.
I thought a steam locomotive should have smoke coming out of its stack so I joined the image of #1621 with this image ☺
