English: Note: The source description of this image has been contested. The carriage has letters ČSD (Československé Státní Dráhy, i.e., Czech State Railways) which operated before World War II, and after); (quite aside from the matter of different gauge widths -- wider in the east ever since the tsarist imperial times -- not a trivial matter even in the second half of the 20th century in terms of rail transpotation/communication between USSR and its Warsaw Pact allies to the west) there is no possible way that ČSD carriages could have ended on Soviet territory because (1) interwar (1918-1939) Czechoslovakia had no common border with USSR (because interwar Poland's territory included present-day Western Ukraine territory that lay between them), (2) by the time the deportations referenced in the article took place (1940-41), Czechoslovakia had not existed for 1-2 yrs -- the Czech lands (Bohemia & Moravia) in the west became Nazi Germany's "protectorate" (effectively, annexed), while a rump Slovakia (Hungary grabbed southern parts of Slovakia) became Fascist puppet state of Germany and its ally Hungary -- neither locales would have retained the call letters 'ČSD' that long, let alone sent these carriages to the Soviet Union. Likewise, the uniform of the soldier overseeing the operation is definitely not a Soviet uniform -- either of the Red Army or of NKVD troops (People's Commissariat (i.e., Ministry) of Internal Affairs); two aspects of the uniform militate against it being Soviet: (1) the garrison cap, and, the (2) collar-lapel combo, specificaly, it dark (black?) framing of/againt the rest of the uniform -- not a Soviet practice. (see attached img -- oops, it did not allow me to attach an img of a Red Army garrison cap and of upper part of the tunic, incl. the collar). As well the luggage is larger and more varied than in the NKVD practice; only one hour or so was given to pack.[1][2]
Source description: Deported Polish families load onto trains to Siberia in Eastern Poland during the Soviet occupation of Kresy in World War II. First wave of mass deportations began on the night of 9 February 1940. The second, on 13 April 1940. The third, on 29 June 1940. And the final fourth one, between May and June 1941. The cumulative number of Polish nationals extracted from their homes and sent to Soviet no-mans land with nothing to live on exceeded 1,600,000.
