Semaphore or Traffic Light?
On the tracks, what do train drivers see ahead of them, a traffic light or a semaphore? Surprisingly, these are different devices created for the same purpose: signaling.
Semaphores came first. They looked like tall masts with moving "arms" that conveyed signals. They were used on railways, and only trained staff could read them. Some had lamps that resembled traffic lights, but in daylight the arms were the only thing a driver could rely on.
Today semaphores are almost gone. Nearly everywhere, theyβve been replaced by round-the-clock traffic lights that are visible in any weather, day or night. A small but elegant upgrade.
P.S. Semaphores waved goodbye, and traffic lights took the signal from there.

The CEO of GC NPS, Alexey Krapivin, and Deputy Prime Minister of Russia Marat Khusnullin have officially launched the construction of the Northern Bypass of Omsk.
At the ceremony, specialists from Mostostroy-11, a GC NPS subsidiary, drove the first pile, marking the start of this major infrastructure project.
The Northern Bypass will be a four-lane highway about 70 kilometers long, designed for speeds of up to 120 km/h. It will connect two federal highways and become part of the M-12 βVostokβ route between Moscow and Tyumen. The bypass will also form an important link in the future corridor from St. Petersburg to Vladivostok, providing access to China and Mongolia.
The project includes two major bridges: a 1,200-meter bridge over the Irtysh River with a 130-meter navigable span, and a 176-meter bridge over the Om River.
Implemented as a public-private partnership, the project agreement between GC NPS and Gazprombank was signed at the St. Petersburg International Economic Forum 2025. The general contractor is Dorogi i Mosty, with Mostostroy-11 as the construction contractor, both part of GC NPS.
P.S. Building a bypass that will surpass all expectations.

GC NPS has reached an important milestone in the construction of the Lavna Coal Transshipment Complex at the seaport of Murmansk. The facilities of Stage 1.2 have now been commissioned.
A Certificate of Compliance was issued, confirming that the completed facilities meet the requirements of the Russian Urban Development Code.
Stage 1.2 includes:
π€ 8.9 km of railway tracks,
π€ a 583-meter berth loading gallery,
π€ five transfer stations,
π€ five conveyor trestles, π€ an open storage area,
π€ auxiliary structures and utility networks.
Since 2021, TEK Mosenergo, a GC NPS subsidiary, has been responsible for the design and construction of the complex on the western shore of Kola Bay.
Letβs recall the key milestones of the project:
π In December 2023, the port received its first coal shipment following the launch of the new VykhodnoyβLavna railway line.
π In November 2024, NPS specialists commissioned the berths and access dam, and in December 2024, the terminal became technically operational.
π On March 27, 2025, the complex handled its first commercial shipment of solid fuel, an event attended virtually by President Vladimir Putin.

The view from a train window is a captivating panorama of landscapes, from winding rivers to rolling hills. But what appears as scenery to a passenger is actually a complex puzzle for the engineer.
Specialized structures are essential where railways meet natural or man made obstacles. The most common are those that cross from above. Bridges span waterways, viaducts conquer deep valleys, and overpasses soar above roads. Smaller yet equally important are culverts, which are channels that discreetly guide water beneath the tracks.
Then there are the passages carved through the earth itself: tunnels. Constructing a tunnel involves far more than simply digging a hole. Each one must be meticulously lined, sealed against water, and equipped with critical systems for ventilation, lighting, monitoring, and fire safety to ensure secure passage.
Finally, holding the line against nature's pressure are retaining walls. These vital structures reinforce steep embankments, preventing soil from collapsing onto the tracks and ensuring the railbed remains stable.
Every journey is a tour of these unsung feats of engineering, the hidden framework that makes the scenery possible.
P.S. The real views are the NPS-built structures along the way.

The Moscow - St. Petersburg high-speed railway project sets new technological standards for the entire transportation industry, said Nikita Terentyev, CEO of Skorostniye Tekhnologii, a GC NPS subsidiary, during the Public Transport Forum 2025.
One of the main challenges faced by NPS engineers in developing the ballastless track technology for HSR-1 was the lack of a regulatory framework. The standards created during the Soviet era are outdated for high-speed applications, while European and Chinese regulations cannot be applied to Russiaβs climate conditions.
For example, a key component of the railwayβs ballastless track, the rail slabs, are manufactured with precision down to tenths of a millimeter. During production, each slab receives a digital marker containing data on its condition, from the concrete mix used to its exact design position along the line. This will enable predictive maintenance of the tracks, helping to reduce operating costs and ensure long-term durability. The entire HSR system is designed to operate reliably and stably for at least 50 years.
P.S. All on track for setting new standards in high-speed transport.

What connects the prophet Moses, Flemish painters, and the legend of the Great Flood?
The answer is asphalt, though not the modern construction material we know today, but its natural form.
The word asphalt comes from Greek Ξ¬ΟΟΞ±Ξ»ΟΞΏΟ , meaning secure or stable. It forms when crude oil seeps to the surface and its lighter components evaporate, leaving behind a thick, sticky residue. Solid at room temperature yet easy to melt, it possesses excellent waterproofing and adhesive properties.
The ancient Sumerians and Egyptians used it to caulk ships and waterproof baskets. According to legend, the Sumerian hero Utnapishtim waterproofed his ark with asphalt to survive the great flood, and the basket that carried the infant Moses was sealed with the same substance.
The largest source of natural asphalt in antiquity was the Dead Sea, which was once known as the Asphalt Lake due to the lumps of bitumen that would regularly float to its surface. This asphalt was of such high quality that Renaissance painters, including the Flemish masters, ground it into a pigment to create rich, transparent browns in their paintings.
Builders in ancient Mesopotamia were the first to use asphalt as a road binder, mixing it with sand and aggregates to pave city streets. In the modern era, the first major large-scale asphalt pavement in Europe was laid on the Champs-ΓlysΓ©es in Paris in 1824.
Today, the world's largest natural asphalt reservoir is Pitch Lake on the island of Trinidad, containing an estimated 6 to 10 million tons, a supply that could last four centuries.
P.S. From the Flood to the freeway, asphalt always finds its way.

On March 13, 1988, the first train passed through Japanβs Seikan Tunnel, the worldβs longest undersea tunnel at 53.85 kilometers. It connects the islands of Honshu and Hokkaido and took 42 years to build.
But why a tunnel and not a bridge?
For many years, the two islands were linked only by ferry. A bridge was once planned, and geological surveys for a tunnel began in 1946. But in 1954, Typhoon Maria sank five ships, including a large ferry, killing nearly 2,000 people. The tragedy ended any plans for a bridge. A tunnel was the only safe option.
The Seikan Tunnel reaches 240 meters below sea level and 100 meters beneath the seabed. When the excavation shield broke down just two kilometers in, workers had to use explosives, more than 2,800 tons in total.
A 23.3-kilometer pilot tunnel connected both shores by 1964, but it took another 24 years to complete the main passage. The final cost ended up twelve times higher than the original estimate.
Today, Japanβs bullet trains travel from Tokyo to Hakodate in about four hours, covering 825 kilometers thanks to this engineering masterpiece.
P.S. Somewhere under the waves, the trains are faster than Wi-Fi.

While Kazimir Malevich is best known for his famous Black Square, he was also deeply interested in color. He spent years studying how different hues influence people both emotionally and physically.
Malevich developed his own theories about the psychological effects of color. He believed that white could intensify pain and suggested that doctors should wear turquoise coats instead.
His most practical idea was directed at workers and builders: bright orange jackets. According to Malevich, orange made people more visible from a distance, even in fog or darkness.
Today, orange jackets are a common sight on construction sites, but in the early twentieth century, the idea was truly innovative.
P.S. Who knew the abstract could be so hands-on?

We use them every day, but have you ever wondered where their names came from? These four types of urban transport have surprisingly contradictory origins.
Bus
The word goes back to omnibus, the Latin for "for all." This was the name of a new transport service in France. The English shortened it to bus. Later, when engines came along, the French and others formed autobus. The meaning changed from "for all" to "self," which is a bit contradictory, but the name stuck.
Metro
London's system was first called the Underground. The first line was run by the Metropolitan Railway, from metropolis, meaning "big city." The French borrowed metropolitan, then clipped it to metro. So today millions of people ride what, taken literally, just means "big."
Tram
In English, tram first meant a wooden beam or rail, then a track for carts, hence tramway, a "track for trams." When rail vehicles began running in cities, the name of the track transferred to the vehicle itself. Other languages borrowed it from there, so now the car and the rails share the same root.
Trolleybus
Trolley originally meant a small cart. When electric streetcars were invented, the rolling wheel and pole that connected to the overhead wires was called a trolley. Over time, trolley became associated with the wire-connected vehicle itself. Combine it with bus and you get "cart bus." Not exactly accurate, but close enough.
P.S. After all, the point isn't what we call it; it's about getting from A to B.
