The completion of the Northwest Railway, which runs across the East Coast grassland, is a milestone event in the history of the East Coast Republic Railway. This 330-kilometer-long railway not only penetrates the hinterland of the northwest inland of the East Coast, but also uses a number of the latest domestic industrial technology achievements, making the quality of the entire railway to a higher level.

Railway transportation technology has been innovated, and the shipping technology that currently occupies most of the East Coast capacity cannot be lagging behind. In a modern special ship factory that has always led the new trend of shipbuilding technology in the East Coast, a brand new large ship has just undergone sea trials and has returned to the dock of the factory for inspection.

It is worth mentioning that this ship is the first fully steam-powered ship in the history of the East Coast Republic. It was launched in November last year. The ship is 72.3 meters long, 10.4 meters wide, 6 meters deep, 4.7 meters draft, and a standard displacement of about 1,300 tons. On this steam ship named "Tahiti", a total of four small boilers and two cylinders (re-upload type, actually 4 cylinders) are installed, forming two re-uploaded reciprocating steam engines, with a total power of about 370 horsepower, driving two propeller propellers. According to the speed estimates during the sea trial, the speed of still water can reach about 6-7 knots, setting a new record for the East Coast.

On the "Tahiti", Viviani, the main designer of the modern special ship factory, adopted the design of a re-swell steam engine for the first time, which greatly improved the steam utilization efficiency. In fact, in the early "low-pressure steam engine" (relatively speaking, it was considered high-pressure compared to the mid-to-earth mid-19th century), the advantages of the re-swell steam engine were not very obvious. However, when Tieling special steel in the northwest inland of the east coast gradually began to produce and ferromanganese smelting was successful, the East Coast steam engine technology once again ushered in innovation.

The application of new materials allows the steam engine to use a larger air pressure to obtain higher output power. In the past, if people from the East Coast wanted to make a high-power steam engine, the only way was to increase the volume and weight of the steam engine, increase coal consumption, and then increase the overall output power of the steam engine. But in fact, the "thrust-to-weight ratio" of the steam engine did not increase, that is, the cylinder pressure per unit area did not increase, and of course the speed of the steam engine did not increase. Therefore, for marine power or land power, its efficiency is limited.

But now everything is different. The steam power system on the east coast is no longer the same as before. The emergence of the manganese iron cylinder has greatly increased the pressure that the cylinder wall can withstand, and the output power per unit area has greatly increased. Since then, it has entered the so-called "high-pressure steam engine" era. Then the design of the re-increasing steam engine with higher steam utilization efficiency has also been put on everyone's agenda.

In the construction of the Tahiti, all cylinders were manganese iron cylinders. The re-surgent steam engine composed of not only had a horsepower far exceeding the past, but also had a speed that was not comparable to the past. This caused a sharp increase in the actual indicator power of the steam engine system. Reflecting on the ship, it was a larger cast iron propeller than before, and the speed was greatly increased. Therefore, without the help of sails and current power, the ship with a standard displacement of 1,300 tons could still be driven at a uniform speed of about 6-7 knots in still water. This is a qualitative leap in the history of shipbuilding on the east coast. What's more, there are so many boilers, cylinders, and propellers on the ship (2). Even if one of them fails and stops working, the ship will not lose its power completely and suffer from danger.

In addition to manganese iron cylinders, people on the East Coast have also applied a lot of new things on their new ships. For example, with the application of new materials, the basic industry on the East Coast has now achieved a leap-up improvement. The service life of bearings, connecting rods, cylinders, gears, flywheels and other components has been greatly enhanced and the accuracy has also been greatly improved. In addition, with the use of a small amount of manganese steel trial-produced through crucibles, manganese steel cutting heads have begun to enter various machining industries on the East Coast. The use of these cutting heads has also effectively improved the processing accuracy of various parts, which is of great significance. After these things are combined, the overall improvement of the machine is huge. In other words, the reliability of the equipment has been improved and the average fault-free time has been extended, which is undoubtedly crucial for all-steam-powered ships.

After the maintenance of the "Tahiti", the old explorer of the East Coast will be led by Zhang Jinhua, a veteran explorer in the east coast, bypassing Cape Horn in the south of Tierra Tierra, and heading to the Port of Araucan, and joining with three immigrant transport ships that are still undergoing major repairs. Then the four ships will carry a small number of people and a large amount of supplies, along the Humboldt cold current, quietly arrive at the Galapagos Islands, and go ashore to supply fresh fresh water. After all this, the four ships will follow Zhang Jinhua's "Tahiti" and sail in the southeast trade wind belt along the warm current of the southern equator, directly to the Tahiti Island that people on the east coast have arrived.

A few people on the east coast who followed the ship will land on the island with weapons, and then try to cut down trees, collect soil and burn bricks, plant food, and strive to repair and maintain the ships passing here in the future. If they are not good, they must provide some fresh vegetables and fresh water. In the plan of the Ministry of Immigration and Admiralty, Tahiti Island is a very important node in the South Pacific immigration route. In the future, a large number of ships will dock here for replenishment, and their strategic position is very important.

After all, the Galapagos Islands are not in the hands of the East Coast people and cannot build any facilities on them. Therefore, this crucial supply and maintenance base can only be moved to Tahiti Island. Ocean navigation ships, especially "quasi-slippers" with relatively high length and width, such as East Coast immigration ships, will not be repaired after a period of time, the chance of damage to the hull and causing shipwreck will be greatly increased. In today's Nantai

Among the flat-circular immigration routes, only Kingsoft Port in Australia and Araucan Port in Chile have the ability to repair and maintain ships, and they are all concentrated in the southern part. Therefore, a repair and supply base is still needed to build a repair base in the north for the ships to be repaired halfway. After the selection, Tahiti Island was selected. This island is located in the center of the southeast trade wind belt, which is almost the center of the entire immigration route. It is most suitable to use it as a repair and supply base.

However, it is not easy to find an island like Tahiti in the vast sea. Even if you know the latitude and general shape of the island in advance, it is still not easy. After all, latitude is easy to measure, but longitude is difficult. At present, people on the east coast rely mainly on the large number of mechanical watches brought before traveling through time and then converting longitude. However, this is not an insurance matter. What if these watches are damaged? Therefore, it has become an extremely important thing to find a way to "copy" these mechanical watches that are far beyond the times in terms of technology and principles.

The sea eagle watch factory, which Mo Ming and Toricaili, jointly started the development of navigation astronomical clocks many years ago, and invested huge sums of money to attract talents. At present, the factory has more than 40 skilled craftsmen collected from Europe and the Ming Dynasty. They designed a high-precision navigation astronomical clock made by Time Travelers as reference (machine production cannot meet the accuracy requirements). After testing, it is very accurate and fully meets the usage requirements. Of course, the size of this astronomical clock is extremely complex and huge, and it is completely incomparable to the precision mechanical watches of Time Travelers. But this is the first astronomical clock produced by the East Coast Republic itself. In the future, many mechanical watches brought by Time Travelers can retire successfully. Therefore, in general, the emergence of the astronomical clock for navigation is still an improvement that cannot be ignored.

In addition to producing the attractive all-steam powered vessels like the Tahiti, the Hyundai Factory has also been driving at full capacity in the past year and has produced many inland steamboats, dredgers, whaling ships, cod fishing ships, ocean squid fishing ships, processing ships, refrigerated ships (Beral/ether refrigeration), lighthouse ships and other types of ships.

Especially the classic 72-ton inland/offshore general steamship has a large load, shallow draft, fast speed, and is deeply loved by users. Now that economic construction is at its peak and logistics transportation pressure is extremely high, it has almost undertaken more than 70% of the material transportation task on the east coast. Modern factory produced more than 40 such small boats in the whole year last year, which has rapidly increased the number of inland steamships under the Orient Republic Institutional River Transportation Company of the East Coast to 127, greatly alleviating the pressure on logistics and transportation and strongly supporting economic construction. In order to keep up with the increase in demand for sailors after the increase in ships, people on the East Coast also frequently made tricks. In addition to recruiting a large number of European and Ming sailors, their own training has never fallen. At present, the number of sailors on almost every civil ship on the east coast is over-equipped, with the purpose of cultivating more reserve talents in case of future emergencies.

In addition, the second type of ships with a huge increase in number are probably various fishing boats, which is due to the consistent demand for seafood by people on the East Coast. Local cheap cod, smooth fish, calamari, and whales are all important components of food consumption of East Coast residents. These demands put great pressure on the Nanhai Fishery Company. Therefore, shipbuilding orders also fly to the three major domestic shipyards on the East Coast like snowflakes. Even the small private star shipyard has received a lot of orders and spent a difficult time when the factory was first built.

In addition to these two, the refrigerated ships ordered by the Nantik Corporation also occupied a large number of shipboards in the four shipyards. Their ships were put into use one after another, allowing various commodities from Nantik, Chile and Peru to be transported to the east coast ports under refrigeration, with a great increase in value. For example, various fishing products along the coast of Chile and Peru (produced in Peru fishing grounds), tropical fruits, animal fat, frozen meat, etc., have created considerable profits for Nantik Corporation.

On February 3, 1650, the "Tahiti" was completed, and then loaded a group of people and a large amount of supplies, slowly left the dock and headed towards the Port of Araucan. After they left, a naval formation composed of several professional warships quietly left the Zhenhaigang Naval Base and headed north.
