2nd Siberian train consisting of two armoured carriages, locomotive and tender.
 
"2nd Siberian" was a variant of the upgraded Hunhuz class, removing casemates and replacing them with platform-mounted long-barrelled 76mm guns in open topped position.  In 1918 the Bolshevik train "2nd Siberian" came up against the White Russian train "Officer". The White forces won this encounter and combined the two trains.
