ARMOURED TRAINS

Part 4.4

Drawings: Locomotives

 

 

The armoured locomotive used in Russian heavy armoured train, that the Finnish White Army captured year 1918, was Russian build. The way it was armoured was much more complicated and effective, than what had been used with locomotives armoured in Fredriksberg Engineering Works and Viipuri Engineering Works for Finnish Red Guards during Finnish Civil War in year 1918. The way Fredriksberg Works armoured the locomotives was very simple - just attaching armour plates to sides of the locomotive to provide protection against small-arms fire both to its steam engine and crew. The locomotives armoured for Finnish Reds in Fredriksberg seemed to have belonged to larger series of locomotives originally known as Mogul. This series belonging to contained four technically quite similar steam locomotive types, Finnish State Railways called these four series G3, G5, G10 and G11. Year 1942 Finnish State Railways (Valtion Rautatiet, abbreviation VR) renamed all these four locomotive series as Sk3-series. The total number of Sk3 steam locomotives manufactured for Finnish use was 88. They were manufactured 1892 - 1905 by SLM, Dübs & Co, Schwartzkopff and Tampella (who was their only Finnish manufacturer). While originally used typically with freight trains Sk3 series locomotives were later used also with passenger trains and last of them ended their career as shunting locomotives. Last Sk3 steam locomotives used by Finnish State Railways were declared obsolete year 1960.

After Finnish Civil only two of the armoured locomotives build for the Reds remained in active use - G5 series number 191 and G10 series number 336. From these two trains at least G10 number 336 remained in use until World War 2. If G5 number 191 was replaced before World War 2 is unclear, but if this happened it this happened its replacement was another Sk3 series locomotive. It is unclear at which point these two Sk3 locomotives were armoured with new much advanced and flexible armour package, but this definitely happened before Winter War. During Winter War Armoured Train 1 (Panssarijuna 1) had G10 number 336 while Armoured Train 2 (Panssarijuna 2) had unspecified armoured locomotive of Sk3 type. These locomotives (and armoured trains) could be easily separated from each other thanks to one notable difference - G10 number 336 lacked the additional tubes used to lead smoke from the smokestack under the locomotive. Before year 1942 Tk3 series locomotives were known also as K5 and with nickname "Konsolidation". Additional K5 series aka Tk3 series locomotive number 884 was armoured after Winter War in year 1940 and it served with armoured trains during Continuation War. Tk3 locomotive was manufactured by Danish Frichs and by Finnish manufacturers Tampella and Lokomo between 1927 and 1953. The total number of Tk3 locomotives manufactured for Finnish State Railways was 161. Those Tk3 locomotives that Frichs manufactured in Denmark were delivered to Finland unassembled and were assembled by Hyvinkää Engineering Works (Hyvinkään Konepaja).
