The Qinghai Tibet Railway line, which was opened in 2006 in the Tibet region of China, passes through the 1955-meter-high Tanggula Mountain pass, built in 5072, connecting the cities of Lhasa and Xining.
Qinghai Tibet Railway locomotives use turbocharged engines that work like a pump that takes the pressure of the gas given out by the custom engine on the line due to the high altitude of movement. In order to get on the train, the passengers must sign a commitment that they do not have any illness due to the fact that the train will go to high altitude, and the train journey continues until Tanggula Pass, with an oxygen supply for each passenger, a doctor for each train.
Kunlun Tunnel
In the works carried out in order to overcome the technical problems in the construction of the railway, the soil on which the rails are laid freezes (permafrost) and in summer, the soil softens from the heat and stretches the track settlement, but the method found is removed by piling the piled foundations immersed in the soil. In spite of climate changes, as in the Trans-Alaska Pipeline System, some parts of the railroad tracks are passively cooled with ammonia-based heat exchangers, providing a safer transportation.
Since the oxygen is 40% lower due to the high altitude in the Tibet region where the train originates, the seats in the wagons are equipped with oxygen sources as in the airplanes, and 44 oxygen supply stations were established along the line and the Kunlun Tunnel in the earthquake zone where the train passes is against the 2001 magnitude earthquake that occurred in 7.3. He showed great strength.
World's Highest Railway Route Tanggula Pass
Avoiding high altitude and earthquake-prone areas in such projects is a priority in establishing railway routes, as a project that can reach Tibet Mountain to enjoy a little nostalgic view at 8848 meters, which is defined as the ceiling of the world without tunneling through Tanggula pass. It reveals the need to be known as a choice to be chosen. An interesting statistic for the railway is that the train could not serve in 5072 because there were no passengers.
For only these two reasons, a railway project to be built in the Eastern Black Sea Region is either the closest and the lowest altitude (2032 meters) to the Black Sea coast in the region, either with tunnels / tunnels to be planned over Zigana Mountain or 1227 km from Gümüşhane at an altitude of 28 meters. The altitude from the sea, which is located at a distance from the sea, suddenly descends to 950 - 1.000 m and from the west of the Kurdun district to 500 meters after reaching Tirebolu and reaching the Black Sea, both the geographical features of the routes and the rich archaeological sites in the direction of Erzincan-Gümüşhane-Trabzon An efficient project will emerge with the fact that it is chosen as a cultural route to revitalize domestic and foreign tourism.
Therefore, the question and problem is that a railway that will pass through the Zigana Mountain, which is the closest province to the Black Sea coast, passes the Zigana Mountain, as a simulation within the road tunnel route, which is still under construction, the high-speed train determined its route by the relevant units of our state with the official survey study. as;
The first one is the road route descending from the west direction of Kurdish up to 1227 meters from the west direction after 950 km on the axis of Gümüşhane (500 meters) -Torul (60 meters) -Torul (500 meters) - The second one is the most on the railway that can be built with the lowest curve angles of the speed. Reaching Torul with a height of 1227 meters from the sea from 950 meters with high speed, reaching Köstere Village at an altitude of 15 meters at a distance of 1250 kilometers, exiting Başarköy at an altitude of 1015 meters with a tunnel like a road tunnel and connecting to Maçka after 17 kilometers
Kunlun Tunnel data, which is built on the Qinghai Tibet Railway passing through Tanngula Mountain, can also be planned with the worst case data that can be taken into account at the time of design.
Erzincan Gümüşhane Trabzon Railway Route Survey Results
The train speed of 160 Km / hour-250 Km / hour envisaged in the official survey project based on the engineering calculations of the revers (slope given to the cross sections of the road) according to the low ramp values of the curves between Gümüşhane and Torul depending on the elevation and turning angles, similar to the road simulation we have drawn above, or With the solutions that can be put forward with better engineering calculations, this railway has a historical relationship with the Köstere Village, which was established by the migration of the Kustere Carving Dulkadiroğlu Turkmens, one of the Bey's families, after the Eretna Principality founded by Uyghur origin Turks in Erzincan was destroyed in 1381. The shortest way is through Gümüşhane, as if to make a plate number, as a nice technical engineering coincidence (!) calculation of the two tubes (each 14.5 Km X 2 tubes) with a total length of 29 Km, the starting point of the Zigana tunnel with the connection to Köstere. Black Sea Region It also proves its transportation to si as an interesting historical companionship.
Despite all these historical, geological and geographic evaluations and the Tanggula Pass, Qinghai Tibet Railway was out of service in 2010 due to the difficulty in finding passengers, it is the most optimum that will provide added value with the intense cultural wealth in Erzincan and Trabzon region, including Gümüşhane. The high-speed train route that will connect to Trabzon and Tirebolu via Gümüşhane, which is the closest point of Erzincan to the Black Sea, also offers us the archaeological codes from ancient times.
