Class 8000 (Locobase 66)

Data from tables in 1930 Locomotive Cyclopedia. See the later and quite detailed overview published by designer Alphonse I Lipetz, "Russian 'Decapod' Locomotives", The Railway Engineer, Volume 43, No 2 (February 1922), pp. 51-54; April 1922, pp. 136-137; July 1922, pp. 249-251; and November 1922, pp. 415-417. (Thanks to a 14 June 2013 email from Chris Hohl pointing out that the Southern actually put numbers on these engines and for his 22 September 2017 email reporting unlikely boiler pressure values for 177 entries. A Locobase macro caused the error .) Works numbers for the locomotives in this entry were Alco's Richmond Works numbers 58837-58846, 58868-58874, 58879 in 1918. (8010 and 8018 never actually operated on the Southern.) Baldwin's works numbers were 48136-48139, 48420, 48466-48467, 48521-48522, 48685 in 1918.

875 were ordered by the Imperial Russian government in 1916; many were delivered and that design was subsequently built in the many hundreds in the Soviet Union. Others went to Japan and 200 stayed in the US. Erie had 75, Seaboard Air Line took 40, Frisco 21, and the rest distributed to 22 other railroads.

Russian decapods allocated to the Southern Railway didn't remain on that road for long. All were reassigned to other roads on 1 January 1919.
