IV Mushketov praised the work of geologists and concluded that the benefits of the Baikal option. Here, all the way from Baikal station to station Kultuk stronger rocks, more favorable conditions for the erosion and weathering of rocks, there is no permafrost. Baikal option is in the best conditions compared with Irkutnym and for tunnels – it needed to build more tunnels, but a small stretch, but on Irkutnom although one tunnel, but big – more than 3,5 km. Thus it was concluded: “Baikal version is much more security and convenience to the railway and therefore should be preferred Irkutnomu.
Complicated geological conditions demanded changes earlier developed the technical specifications. Thus, a reduced radius curves up to 150 fathoms (320 meters). Elevated position of the red marks on the level of not less than 5 – 6,5 m above low level of the lake (to protect the roadbed from the splash of a wave). It was decided to pave the road line based on topography coast, the state of rock and water depth, use retaining walls to protect from the waves and avalanches of rock, to establish fences, embankments and tunnels for protection from the talus.

The final survey along the Circum-Baikal railway were carried out in 1899 – 1900 years. led BU Savrimovicha. They involved three geological parties, for which the program was an outstanding geologist Professor IV muskets. He, after a detailed examination of the route in two variants and analysis of the geologists of the materials gave a conclusion. Covered options: Baikal (Irkutsk – Port Baikal – Kultuk) and Irkutny (Irkutsk – the rise in the valley. Irkut – Mountain Pass with tunnels – Kultuk). The trail went along the shore of the lake to the station capes. For each of the two options to Kultuk geologists have established the geological structure “to an extent which is required for the most detailed geological studies and gathered extensive collections of rocks (more than a thousand samples), occurring on the highway.

In this connection, it took a reality check of their proposals. In 1888 – 1889 years. in these places worked Transbaikalia expedition OP Vyazemsky. All three of her party were literally swamped with work. The results of the exploration carried out by Colonel General Staff, NA Voloshin, showed that: there is no accurate maps of the area that exist have a lot of mistakes, it turns out the general nature of the terrain and climatic conditions of the region. It turned out that the North direction not only shorter than the South, but on the contrary, the 400 miles to its length. However, only in one section of the Angara-Baikal line must cross five major rivers – the Angara, Ilim, Lena, Hand and Kirengu and five Dividing Range – Ilim, Berezovsky, Lenski, Kirengsky and Muya (with notes on water level in rivers 200 – 900 m). Intelligence led NA Voloshin concluded that when choosing the direction north of Lake Baikal “the construction and operation of the road will cause undue hardship and excessive costs.” By the way, it’s all confirmed in the construction of BAM.

Technical specifications for the device trips measured bandwidth of the road in 14 pairs of trains per day. Due to the lack of coastal terraces delivery of all materials to the construction site (except stone, quarried locally) was carried out on the water (in the summer – on barges, in winter – Cartage go on the ice).
In this case, the construction of bridges and other engineering structures instead of natural stone was actively used for those times a new material – concrete.
Survey of the road. Preliminary investigations Circum-Baikal railway engineers were expeditions OP Viazemsky and GV Hadrian. They chose a direction, bypassing Lake Baikal in the south. General AP Protsenko in 1887 issued a pamphlet on the need to build a continuous railroad from Central Russia to Vladivostok with the laying of the Circum-Baikal north of Lake Baikal. A similar proposal put forward engineer NL Mezheninov, who argued that this line will be 550 miles shorter than the south direction, with the best parameters of its construction. The authors of these proposals are no surveys are not conducted, the conclusions were based on maps.

Initial exploration work was carried out with the participation of AI Shtukenberg in 1836-1840, respectively. The final stage of the determination of the route the first section of Circum-Baikal from Irkutsk to Lake Baikal, was held in 1894. The final decision on the passage route taken by the Committee on the construction of the Siberian railway June 9, 1901. The estimated construction cost of the Circum-Baikal railway segment totaled 52.52 million rubles. Beaches are a rocky ridge with steep slopes, towering over the water’s edge at 270-400 m The original plan, the section from Slyudyanka to P. Baikal was necessary to build a 33 tonnelya.Minimalnaya height proleganiya railroad tracks on the shoreline of Lake Baikal – 5,33 m.

A small illustrated essay on the Circum-Baikal railway, the history of its construction and modern state.
Circum-Baikal Railway – historic railroad in the Irkutsk region, in the past – part of the Trans-Siberian Railway, a unique monument of engineering, one of the most picturesque sights of the Baikal region. Runs along the northern coast of the southern tip of Lake Baikal from the city Slyudyanka to the village of Lake Baikal in southern Olhinskogo plateau. After commissioning, the backup site Circum-Baikal railway lost its former importance. Section of road from Irkutsk station and screening to the port of Baikal, which took place on the left bank of the Angara, was dismantled in 1956 and completely flooded in 1958 after construction of the Irkutsk hydropower plant, in the process of filling the Irkutsk Reservoir.
Siberian railroad, later known as Trans-Siberian Railway, the design was divided into seven sections, among which was the Circum-Baikal, a route which was supposed to go from Irkutsk to the pier Mysovaya (now the city Grandmother) on the eastern shore of Lake Baikal.

Ubiquitous wireless access to the predominantly cellular and the Internet – an undeniable achievement of mankind. However, not everyone knows that the benefits of civilization cause some people discomfort in the form of headache, dizziness, insomnia, fatigue, reduced performance and even depression. The degree of ill health from electromagnetic radiation of high-voltage lines and wireless networks depends on network density and constitution of man. And if the radiation dose from TV, radio, cordless phones in their own home can be limited by abandoning the use of standby equipment, a significant portion of the electromagnetic waves will continue to receive a home through the power wires and radio masts. New development – the shield of non-woven fabric based on carbon – will provide better protection against elektrosmoga. Coverage is available in rolls measuring 1 x 20 m and pasted on the wall like wallpaper on a well-leveled base after painting or priming. Protective material “breathes”, will not crack and is a good alternative to fiberglass or PVC. Interested in the services of freight? Then for you a very interesting proposal. Delivery of goods to the company AsstrA – a tempting offer. Services are provided between Europe, China and the CIS, as well as CIS countries and Belarus. Just selects the optimal route, which will allow customers to save money.

“Several years ago I could not imagine that in the streets of Yakub Kolas before the war there were intelligent life forms (exaggerating, but still). Now, well acquainted with the history of this area, I can responsibly say that in the 1930’s in this direction Minsk stretched pretty far, reaching almost to the Sevastopol park, and very few did not reach the border of Minsk today (for comparison: in the north Minsk-west direction ended just after Stella) …
