Ps. starting point notice, tomorrow the history channel will push my work, these two days I am going to work overtime to catch up with a few more chapters, to thank you for your support in the past few months.

This was Sergey's second visit to Berlin and his second visit to Berlin's Frankfurt station (Berlin's Ostbahnhof station was called Frankfurt in this period).

Due to the original planning, Berlin's Ostbahnhof, also known as Frankfurt Station, became the starting point for passengers travelling from Berlin to St. Petersburg or Moscow through its connection to the Prussian Eastern Railway.

If you want to go west to Paris, you need to go to the Berlin Zoo train station (Berlin Westbahnhof), and if you want to go around Hannover Hamburg, you need to go to Spandau train station.

Frankfurt Railway Station is a neoclassical railway station, without the complicated decoration style of Baroque or Rococo, but a railway station with simple and clear lines and a minimalist style.

The tall dome of the station hall is a wooden structure with curved arches at the entrance and exit. The building itself is made of heavy masonry concrete, with vertical wall columns and colonnades forming a simple internal façade. The walls are decorated with beautiful grey Oamaru limestone.

The round-arched walls close to the dome open with huge grid-like windows, and the lintels and entrances to the doors are beautifully decorated in relief.

Because there was no concept of a train hub in Europe at this time, Frankfurt Railway Station had only eight bay platforms (Kopfbahnhof) instead of a through-train station like a transport hub.

Since the locomotive could not be towed at both ends, the steam locomotive that came to Frankfurt station had to make a U-turn, so at the other end of the station there was a huge rail turntable for the locomotive to turn.

In the late spring of 1879, even in Berlin, which was already one of the centers of Europe, the German railway network was not sufficiently developed, especially because of the limitations of communication technology and the lack of large hub-like railway stations. Especially in a central city like Berlin, there should be a Berlin Hauptbahnhof similar to Joey's previous life.

General Shuvalov, Chairman of the Council of Ministers of Russia, and Sergei, Grand Duke of Moscow, rode on the Tsar's special train, a huge train set of 15 cars, which was also a luxurious delegation of more than 100 servants alone.

Sergei, who arrived in Berlin near dusk in the continuous spring rain in Berlin, immediately found that the current Frankfurt station was very different from his impression five years ago as soon as he stepped on the platform of Frankfurt Station.

Before electric lighting was widespread in Europe, public lighting was either gas or kerosene, and Sergei was familiar with the dim light and unpleasant smell of these two types of lighting.

But today's Frankfurt railway station lights are clearly as big as gas lamps or kerosene lamps, some of which are as hot as the sun in Sergei's eyes, so that Sergei does not dare to look at them directly, while others are much softer, like a warm spring day with a soft yellow glow.

The lamp that Grand Duke Sergei couldn't bear to look at was not the incandescent lamp invented by Edison, but a more primitive electric lamp, the arc lamp, a brush-type arc lamp that ignites by breaking through the air.

The lamp, which emits a soft yellow light, is an incandescent lamp that uses an electric current to pass through the filament to heat the filament to an incandescent state, and converts heat energy into light energy.

In fact, the inventor of the incandescent lamp, not the legendary one, used a mirror to reflect candlelight to illuminate his mother's surgery, or was slapped by the conductor (all fake!). Edison.

It was the Englishman Joseph Swan, who exhibited the first commercially significant carbon filament incandescent lamp at the Newcastle Chemical Society meeting in December 1878, and Edison's first incandescent lamp did not appear until October 21, 1879.

Under Joey's reminder in early April, the Siemens brothers quickly gave up the continued research and development of brush arc lamps and decisively turned to the direction of incandescent lamps.

At the prompting of Professor Helmholtz, the Siemens brothers went to Gateshead in Newcastle all the time, found Sir Swan, and directly spent a lot of money to buy the patent rights of incandescent lamps on the European continent, and at the end of April, in the laboratory of the Siemens brothers, the first batch of incandescent lamps with carbonized parchment as filament were successfully produced.

The life of this batch of incandescent lamps can only last for less than 4 hours due to the vacuum degree and the life of the filament material.

Such a short lighting life was not what Joey expected. Immediately, based on what he knew in his previous life, Joey took out the final material used in Edison's incandescent filament, directly crossed the experimental process of Edison's exhaustive method in history, and found a suitable filament material for the Siemens brothers.

Based on Sir Swan's carbonized parchment, Joey directly planned for the Siemens brothers three stages of materials, from the most easily found carbonized cotton thread, to the medium-difficult carbonized bamboo wire (also selected from Japan), and the most difficult metal tungsten wire.

On the first day of May, the carbide cotton thread incandescent lamp produced by the Siemens Brothers laboratory changed from a mere 4 hours of Sir Swann incandescent lamps to 45 hours of Siemens incandescent lamps.

Joey assured the Siemens brothers that if the carbonized bamboo filament was further replaced, supplemented by a platinum contact wire, and the filament took the shape of the letter M in a vacuum bulb, the incandescent lamp would be lit for 1,200 hours.

At Joey's suggestion, the Siemens brothers, who finally found the right direction for the development of incandescent lamps, actually saved the students in East Asia in the future, so that they no longer have to write about the false stories of Edison as a child, and there will not be so many articles about Edison's chicken soup.

Now that Edison's invention has been robbed, Joey is no longer polite, and at Joey's strong suggestion and funding from the Crown Princess Victoria Foundation, Siemens (North America) Electric Company, or SAE, was founded in New York in May 1879.

According to Joey's idea, with the help of the light of the incandescent lamp, it is necessary to let the Americans use 230V alternating current to completely bury Edison's 110V fallacy and heresy, otherwise how can it be right to let Siemens invent the incandescent lamp in 1879!

It would take five months for Edison to find the incandescent lamp of the carbide cotton filament, which was enough time for the Siemens brothers to register the patent and start the company.

What's more, the existence of the great General Electric Company will be questionable.

The General Electric Company, which historically held the title of the Optoelectronic Empire, must now give the title of the Optoelectronic Empire to Siemens Electric! Joey is happy just thinking about it.

Originally, according to the meaning of the Siemens brothers, they first used this batch of carbonized cotton thread incandescent lamps for the decoration of their own houses and used their own houses to advertise, but Joy thought that since they wanted to advertise, they should put advertisements in the places with the most foot traffic, and the places with the most people in the nineteenth century were only train stations.

Eventually, at Joey's strong suggestion, and even at some brutal request, Crown Prince Frederick's coordination was able to use the incandescent lamps at Frankfurt train station just after mid-May.

Why did he choose to use Frankfurt train station first, instead of Zoo station or Spandau station, Joey's explanation is very capricious, since the Russians used soldiers to show their muscles to Germany, then the civilized people of Germany should use technology to show strength to the Russians.

So the Grand Duke of Moscow, Sergei Alexandrovich, in the dusk drizzle at the Berlin train station, was honored to see for the first time, arc lamps as bright as the sun, and incandescent lamps as warm as a spring day.

It was also the first time that incandescent lamps appeared on a large scale in a public building (the first person to light incandescent lamps on the street was Sir Swan), and these lights shook the guests from far away Moscow as Joey had hoped, and completely conquered Sergei's heart in an instant.

Count Bernhardt-Ernst von Blo, Secretary of State of the Imperial Foreign Office, who had come to welcome the Russian guests, smiled reservedly and proudly as he looked at the Russian guests who were just looking up at the dome of the railway station.

"Ha, through science to show strength, this method is not only elegant but also effective, this group of hillbillies are just like themselves a few days ago, looking up stupidly.... Oh, so did you wrap myself in it too? Count Blo was suddenly a little puzzled by what was in his mind.

After lingering for a long time, the Russian hillbillies in the eyes of Count Blo finally left the train station.

Sitting in the carriage bound for the most luxurious hotel in Berlin, the Hotel Roma, General Shuvalov, who was a little dizzy from looking up for a long time, was obviously not as excited as the Grand Duke Sergei opposite.

Five years ago, General Shuvalov was also part of the Russian delegation to Germany, and General Shuvalov vividly remembers how the Germans warmly welcomed the Russian guests at the Frankfurt railway station.

Although the Germans are just as polite as the Germans should have at the Frankfurt railway station today, General Shuvalov can clearly feel the alienation of the Germans and the silent demonstrations.

Most importantly, in the past, Germans liked to wear Russian uniforms to welcome Russian guests, but today all honor guards and guards are all Prussian blue.

Of course, General Shuvalov knew that everything today was due to the old Tsar's plan to increase troops in the west a few weeks ago, but without this plan for this increase, General Shuvalov, who was in charge of the Third Department of the Moscow Police, knew very well that Russia's ass was sitting on the crater of an imminent eruption.

On the surface, the old tsar was assassinated only 5 times, but in fact this is only the tip of the iceberg, and those that were not carried out, or were strangled by General Shuvalov in the back, there were at least hundreds.

Especially after last year's Berlin Conference, various assassinations have been carried out one after another, making General Shuvalov anxious.

However, after the old tsar's brilliant stroke, the tension in Russia has been significantly eased in the past few weeks, and many assassins and assassins have been told one after another, and the whistleblower is actually the closest person to these assassins, and the reason for the whistleblower is actually someone who tried to hurt my "old father".

"Now shouting old dad, but before you wanted to eat meat and drink blood, you bastards of the Narodnik Party and the Populist Party!" Thinking of this, General Shuvalov couldn't help but curse in his heart.

The removal of Ignaev and his replacement with General Shuvalov is an important personnel adjustment by the old Tsar's genius to change the government from anti-German to pro-German, and with the help of General Shuvalov's always pro-German stance, he tried to repair Russian-German relations and then sign the Three Emperors Alliance.

After all, the current world is still in the stage of competition for hegemony between Russia and Britain, and if they can rely on a continental alliance that also belongs to the monarchical system, it will be more confident for the Russians to compete for hegemony with the British.

Before coming to Germany, General Shuvalov, through Foreign Minister Gorchakov, who had already arrived in Berlin early, under the command of the old Tsar, the Russian monarchs and ministers staged a double play, and through diplomatic efforts to create tensions, not only did they trap the French money, but also secretly forced the old prime minister to support Crown Prince Frederick's agreement to reduce tariffs on Russian grain.

Therefore, with his excellent populist performance and the reduction of grain tariffs, General Shuvalov was very popular at the beginning of his reign.

Encouraged by this public opinion in Russia, General Shuvalov was very high spirited before coming to Germany, and not only hoped to make another breakthrough in the diplomatic field that he was good at, such as gaining the Germans to support Russia in the confrontation between Russia and Britain.

Moreover, after learning of the economic measures taken by Crown Prince Frederick to encourage German domestic demand, he hoped to make breakthroughs in other fields, such as trade and industry, and his greatest ambition was to allow the Germans to purchase the industrial products of the Russians.

But what he saw today at the Frankfurt railway station made General Shuvalov feel that it would be a little, seemingly, probably, certainly difficult for the Germans to buy the industrial goods of the Russians.

As the chairman of the Reich Council of Ministers, he could not afford to neglect domestic, foreign, and economic affairs, and now that his status was high and his responsibilities were heavy, he could only hope that his pro-German title would allow his German friends to help him.
