Sources: There are a Bronze Age matted burial mound height in to the West from the selo; and a Bronze Age ploughed up burial ground of three mounds in South-West from the selo. According to local legend, the name of the selo came from a large lake surrounded by pine trees. Definitely one can only say this is area of pinewoods. ===18th century (
Russian Empire)=== Three settlements were founded on the place of present-day selo in the early to the middle of the 18th century, before 1721: • selo Rozhdestvenskoye (), or Sosnovka (, "Piny Village"), founded by landlord colonel (
polkovnik) prince (
knyaz) Fyodor Grigor'yevich Tyufyakin (); 84 "census souls" were in 1747 • sel`tso Rozhdestvenskoye (), or Mitkirey (), founded by landlord prime-major of the 1st Moscow Regiment Pyotr Grigog'evich Plemyannikov (); 88 "census souls" were in 1747 • sel`tso Rozhdestvenskoye, or Sosnovka, or Mitkirey, founded by
Cathedral of the Annunciation, Moscow; 288 "census souls" were in 1747. Peasants came from
Nizhny Lomov,
Penza,
Shatsk,
Moscow,
Saransk,
Yaroslavl,
Simbirsk districts (
uyezds). 460 "census souls" were in 1747 in all. In 1747 these three settlements were in Zaval'niy stan of Penza District (Uyezd). In 1780 these settlements were included in
Serdobsk District (Uyezd) of
Saratov Governorate (Guberniya). It was a rich trade place. According to the map of General Land Surveying of 1790 Two settlements were situated on this place in the late of the 18th century: • selo Rozhdestvenskoye, or Vlasovka; it was a mistake of the map-maker, correctly is Sosnovka • selo Troitskoye (, "Trinity Village"), or Sosnovka In 1795 selo Troitskoye, or Sosnovka consisted of three parts: • estates of economic peasants 181 farmsteads, 758 "census souls" • estate of lieutenant (
poruchik) Ivan Andreyevich and Guards ensign (
praporshchik) Nikonor Andreyevich, princes Divletkildeyevy, 42 farmsteads, 152 "census souls" • estate prince (knyaz) of Sergey Fyodorovich
Golitzyn, 17 farmsteads, 89 "census souls".
From 19th century to 1917 (Russian Empire) In 1811 one part of the selo was inhabited by state peasants (677 "census souls"), another part by
praedial serf of general-major Sergey Fyodorovich Golitzyn (89 "census souls" on 586
desyatinas and of princes Ivan Andreyevich и Nikonor Andreyevich Divletkildeyevy (152 "census souls" on 1219 desyatinas). Prior to the
Abolition of Serfdom (1861) one part of selo Troitskoye belonged to prince N. N. Divlet-Kil'deyev. There were 105 "census souls" of peasants, 8 "census souls" of house-serfs, 31 ½ impost units, tyaglo (in
corvee labour). Peasants used 23 farmsteads on 12,6 desyatinas of farm land, 255,8 desyatinas of ploughed fields, 29 desyatinas of hayfields. Landlord had 304 desyatinas useful land, including 152,4 desyatinas of forest and bushes. In 1859 there were fair and market. At Eastertide people saluted with gun by tradition. After Abolition of Serfdom former landlord's peasants redeemed the land. Up to
collectivization (1928—1937) peasant community divide into three associations ("societies"): • the 1st of former peasants of landlord Prozorovskiy-
Golitzyn • the 2nd of former peasants of Divletkil'deyev and Artsybashev • the 3rd of former state peasants. By the end of the 19th century were made new streets. About 1872 was made Latyshovka street (nowadays Sadovaya, "Garden" street). According to local legend, the name of the street came from certain
Latvians, who had settled on this place. Nowadays Khopyornaya (
Khopyor) street was called Nakhalovka ("Impudent") st., because a certain man settled without permission ("impudently") near forest. Later it was renamed to Khopyornaya, because it is situated near the Khopyor River. There were water and wind mills, well-developed animal husbandry, pottery and tanning industry in Bekovo region, and the waterway on the Khopyor River. Landowners and industrialists Ustinovs, who owned many lands in Bekovo region, have vast contacts in trade and industry. All that facilitated development of trade in Bekovo region and communication with other places. In 1871 railroad and Vertunovskaya railway station were built (see below). Since 1877 the selo had been the center of
volost' of Serdobsk District (Uyezd). There was volost' administration, 376 farmsteads, one church, 5 shops, market on Fridays. In 1903 railway lunchroom and railway club-house ("people's house") were opened. In 1911 in the selo there were 642 farmsteads, one church, schools (see below), post-and-telegraph office, market,
machine and tractor station, mill and brickworks.
The church The church was built in 1880 in the geographical center of the selo on the upland near the cemetery. It was built from pinewood The church was visible from afar. The house of priest and
deacon was near the church. The church burned down in 1903. The cause of the fire is unknown. The church was built again by insurance premium in 1915 and
dedicated on 27 June. The church might be destroyed in the first decades of
Soviet Period. ===Soviet Period (
Soviet Russia and the
Soviet Union), 1917–1991=== After
October Revolution (1917) peasants worked at
kolkhozes, brickworks and railroad. Many people worked in town

There were an ambulance station and pharmacy. Later the ambulance station attached to the Vertunovskaya railway station was opened. About 1930–1932, a maternity hospital attached to railway ambulance station was opened. Also, there were a post office, market, mill, granary, vegetable store cellar, liquor shop, railway lunchroom and railway club-house ("people's house"). During

It was situated in the former house of priest and deacon. Fire-tower was situated near this place. In Soviet Period there were three primary schools: • in the Barskaya ("Barin's") street (in the former house of mistress of landlord Tyufyakin) • in the center of the selo, it was the former zemstvo school • in Zalinia, in the Pochtovaya ("Postal") street, it was attached to railway organization. In 1930 primary/secondary school was opened in Zalinia, it had with 7 grades and called school of peasant youths. It was situated in two former buildings of landlord Smirnov. Later the third building was made. Pupils were also from all of the local primary schools: from the settlements Kryukovka, Vlasovka, Malyonovka, Podsot, Sennoy Ovrag ("Hay Ravine"), Pervoye and Vtoroye Otdeleniye (settlements of the First and the Second branches of Sosnovskiy sovkhoz) – there were many children. Children of the selo also learned in the secondary school of Sakhzavod, opened in 1955. After Second World War shortage of labour was, and women were called to renew destroyed equipment. Therefore, nursery and kindergartens was opened. The nursery was opened in 1948 and was attached to selsoviet. It was situated in private house in the Bol'shaya street. To 1956 building for nursery was made. In 1967 nursery-kindergarten attached to Sosnovskiy sovkhoz was opened. About 1970s nursery-kindergarten No. 120 was opened, it was attached to railway station and situated in the building of the former school No. 86 attached to railway organization. ===
Kolkhozes and
Sovkhoz "Sosnovskiy"=== In 1923 some inhabitants were to resettled to
khutor (hamlet) near the forest, where
distillery of Smirnov was situated. Khutor was named Krasnyy ("Red"). It was a lot of vacant lands, therefore farming artel' "Krasnyy Khutor" was established. Farming artel' was organized by
twenty-five-thousander Nikolay Vasil'yevich Lizunkov. In 1929 the artel' got a first tractor
Fordson. In 1930 was established large Kolkhoz of
Kalinin, including Sosnovka and village Sennoy Ovrag. Chairman of the kolkhoz was twenty-five-thousander I. D. Kalinkin. Since 1955 Sosnovka became a central farmstead of Kalinin Kolkhoz. Later the Kolkhoz of
Voroshilov and Kolkhoz "Pobeda" ("Victory") were established; they included some settlement: Malyonovka, Podsot, Vlasovka, Soglasovka, Kryukovka. Kolkhozes existed up to 1959. Kolkhozes included farms. One of the farms was situated between Big st. and Kuznechnaya ("Blacksmith's") st. near the dairy point. In February 1960 kolkhozes were united in Sovkhoz "Sosnovskiy".

Sovkhoz specialize in production of grain, meat, milk and
sugar beet. There were
separator point, power-saw bench, forge workshop and repair workshop of agricultural machinery.
Railroad In 1871 railway line Umyot –
Atkarsk and Vertunovskaya railway station were built (the name Vertunovskaya is from neighbour selo Vertunovka). Vertunovskaya station were included in
Ryazan-
Ural Railway. Towards 1881 the railway station was state. In January, 1892 года government give the railroad to private company. Large company Joint-Stock Company of Ryazan-Ural Railway was found. The railroad contributed to the development of Sosnovka. Sosnovka—Bekovo (Vertunovskaya-Bekovo) railway branch was built by industrialists Ustinovs. It was put in operation in 1874. Bekovo branch was the first in Russia, which was built at private expense.
Ministry of Finance and Ministry of Communications couldn't decide, to give license for the building or no. The license was received on 22 February 1874, but by that time the branch was already built. In early March the railway communication began. Ustinov put the branch into operation to
Tambov-
Saratov Railway. The branch was leased by state. Later Tambov—Saratov Railway became state, and Ryazan-Ural Railway was found. State
Kozlov-Saratov line was passed to Ryazan-Ural Railway. State bought Bekovo branch for 800 thousand
rubles and it was passed to Company of Ryazan-Ural Railway. When Bekovo branch was gone into operation and trade grew, including corn-trade, Bekovo became the largest trading centre in Serdobsk District (Uyezd). After construction of the railway Sosnovka grew quickly. Large part of the population worked at construction and service of railway tracks. After October Revolution semi-automatic block system was brought in at Vertunovskaya station, railway tracks were reconstructed. Since the sugar factory (Sakhzavod) went into operation in 1933–34, density of freight traffic grew. Railwaymen contributed greatly to victory in the Second World War (1945). Railroad engineers Aleksandr Nikitovich Shchavelev and Dmitriy Ivanovich Tarantin, who were born in Sosnovka, fell in pursuance of military missions. There was large goods traffic on railroad, but railwaymen handled a task. After the Second World War density of freight traffic grew. The number of railway tracks was increased at the station, from three to six. All-electric interlocking was introduced (it cancelled work of pointsmen) and radio communication with railroad engineers. ==Economy==
