# Armoured trains of Poland

Armored trains of Poland mostly date to the World War I period. Many of them were modernized over the next two decades, and took part in most military conflicts of the Second Polish Republic, namely the Greater Poland Uprising, the Polish-Ukrainian War, the Polish-Bolshevik War, the Silesian Uprisings and the Polish September Campaign in World War II. Armored trains were also used by the Polish Armed Forces in the West as well as in the post-war period by the Polish Railroad Guards (Straż Ochrony Kolei) and the People's Army of Poland.

## 1918–1939

The first use of armored trains by Polish forces dates to late in World War I and the Russian Civil War period (1918–19), when Polish Armed Forces in the East (Polish I Corps in Russia and other units) operated seven different armored trains (six improvised and one captured).
From 1918 through 1920 the newly created Polish Army received about 90 armored trains, mostly from workshops in Kraków, Nowy Sącz, Lwów (Lviv), Warsaw and Wilno (Vilnius). Many of them were classified as improvised, and consisted of regular trains and wagons armored with metal gates, cement and sandbags; the soldiers called them "mobile trenches". Some equipment came from the Austro-Hungarian 3rd Armored Division, whose equipment was acquired by a unit of the Polish Military Organization.
Several armored trains fought supporting the Polish forces in the Greater Poland uprising (1918–9) and the Polish-Ukrainian War (1918–19). The armored trains saw major action in the Polish-Soviet War (1919–21). Approximately 50 armored trains participated in that conflict on the Polish side; on average, about twenty were in active service at any given time. Sixteen armored trains supported the Polish insurgents during the Third Silesian Uprising.
In 1921 the armored trains forces were reorganized into 6 divisions, each composed of two trains, attached to train engineers regiments (1st in Kraków, 2nd in Jabłonna (Legionowo) and 3rd in Poznań). In 1924 the 3rd Regiment was disbanded, and the remaining armored train divisions were transformed into the Armored Trains Training Division in Jabłonna (Legionowo). The Training Division, in 1925 renamed to Educational Division, in 1927 was reorganized into the 1st Armored Train Division. In 1928 the 2nd Armored Train Division was formed in Niepołomice. Each division had 6 trains. In 1929, the Polish Engineering Force was reorganized, with the 1st and 2nd Train Engineer Regiments being transformed into Train Bridges Battalions.
In 1931 the modernization of armored trains was finished with similar armament installed on most units. The trains were classified as either "light" or "heavy". "Light" trains had two artillery and one infantry wagons, and World War I-era Austro-Hungarian or Russian weapons (two to four 75mm guns, eight to sixteen heavy machine guns, and two anti-aircraft heavy machine guns). "Heavy" trains had a better engine (Ti3), 100mm guns in addition to the 75mm pieces and gun turrets for the heavy machine guns. The trains were also accompanied by several light tanks (FT-17s or tankettes). Each train had its own supply train that contained living quarters, kitchen, workshop, a compartment for the wounded personnel, and supplies. Together, a train (combat and supply) had a crew of 8 officers, 59 warrant officers and 124 regular infantrymen. Around the mid-1930s, revisions to Poland's tactical and strategic doctrines meant that armored trains, previously considered a high-quality force, begun to be seen as increasingly obsolete on the battlefield.

## 1939–1945 (WWII)

The ten trains of the 1st and 2nd Armored Trains Divisions were mobilized in late August to early September, and received numbers 11–5 (1st Division) and 51–5 (2nd Division). With the exceptions of trains 14 and 15 which finished forming on 3 September and were assigned to the reserves of the High Command, all other trains finished forming before the start of hostilities on 1 September. The 2nd Division also fielded a lightly armed training armored train, although it was not supposed to be used in the frontline combat.
The command of the Land Coastal Defence decided to field improvised trains to bolster its defenses. The first was ready before the war began, two others were finished during the hostilities. They used weapons from the Riverine Flotilla of the Polish Navy and the unfinished ORP Orkan and Huragan destroyers. The first train was destroyed after four days of fighting on 4 September, the second, less than a day after it entered service (it entered service on 3 September and was destroyed on the night of 3 to 4 September). The last train, "Smok Kaszubski" (Kashubian Dragon) entered combat on 7 September, and was operational till 12 September.
On 20 September, during the siege of Warsaw, two improvised armored trains were formed (Nr. 1 and Nr. 2). Not much is known about their combat operations; the first train entered service on 22 September, and the second a day later.

During the Polish September Campaign, Polish armored trains took part in roughly 90 clashes with the German units. They played a significant role in several encounters, most notably, no 53 made an important contribution to the Polish victory in the Battle of Mokra, and no 54 was used very successfully in the defense of Silesia. Armored trains were responsible for destroying or damaging several dozens of armored vehicles, including tanks, shot down or damaged three airplanes, and inflicted numerous infantry casualties. Only two trains (no 11 and 55) were destroyed in direct combat by the German land forces, and only no 13 was destroyed by the German air force. Remaining trains were abandoned and destroyed by their own crews when they ran out of munitions and could no longer retreat. The successful role of the armored trains, considered obsolete by both Polish and German strategists, caused the revision of that judgment by both sides.
About a dozen Polish armoured trains in Britain were formed by the Polish Armed Forces in the West, and were assigned to patrol the British railways in 1940. They saw no combat, and were disbanded by July 1943.

## 1945–1952

After the war, in the Republic of Poland, Railroad Guards (Straż Ochrony Kolei) used four armored trains from 1945 to 1950. In 1947, a Train Artillery Division was formed, and disbanded in 1952.
