P.S. NPS

NPS and Russian Railways have started field tests of the HSR ballastless track at their new site. This marks the first time the track was assembled in field conditions.

NPS workers installed 207 NGP 4.0 rail slabs, with a robotic total station checking their position in real time to within a millimeter, letting them lay 24 slabs a day. Two turnouts by Eltesa, an NPS subsidiary, are also installed, enabling remote and automatic switching with continuous diagnostics. The track is now being tested under the load of an operating high-speed train, with several cars converted into a mobile lab to assess ride smoothness and infrastructure impact.

NGP 4.0, the key element of the system, is a composite slab of high-strength concrete and elastic polymer with a 50-year service life, engineered for fast repairs within short night windows. The test results will confirm the track structure’s design specifications, help refine installation and operation technologies, and prepare engineering solutions for use across the entire first Moscow–St. Petersburg HSR line.

P.S. Precision first, velocity after.

This narrow-gauge railway near Melbourne, the kind of train Harry Potter might have ridden had he grown up in Australia, was slated for the scrapyard by the mid-20th century. Volunteers had other plans, and today it’s one of the country’s most beloved tourist attractions.

Puffing Billy was built in 1900 for local farmers and loggers, winding through the forested Dandenong Ranges. As roads expanded, the line was deemed unprofitable and nearly shut down, but volunteers stepped in and kept it running, not as transport, but as a journey back in time.

The tracks, the uniforms, the original coal-fired locomotives, fully restored, all still belong to another century. Carriages keep the old style too, letting passengers sit on the ledges, legs dangling as the scenery rolls by. Even the wooden trestle bridges are original, the grandest being the Monbulk Creek trestle, rising nearly 13 meters above the ground

P.S. Stopped serving transport. Started serving memory.

More than 30,000 specialists from NPS companies are working on Russia’s first high-speed rail line between Moscow and St. Petersburg.

Based on NPS HR data, men make up the majority of the workforce, most commonly named Alexander, averaging 41 years old, typically married with two children and holding vocational education, with the most common roles being drivers and train operators, fitters, concrete workers, and laborers. Women account for around 10% of the workforce, mostly engineers, designers, warehouse staff, and dispatchers, though some also work as fitters, forklift operators, and excavator operators. Nearly a third of workers are under 35, and by the WHO’s broader definition of youth, extending to age 45, the HSR is almost entirely a young people’s project.

The project applies first-of-their-kind engineering solutions in Russia, including next-generation ballastless slabs and multi-ton bridge girders, with digital monitoring at every stage. As a result, traditional trades are picking up digital skills, and new specialties are emerging around digital twins and autonomous construction equipment.

P.S. Thousands of builders, one breakthrough for the future.

Every eight years, trains in Japan’s mountain regions come to a halt. The cause is not a signal failure, snowfall, or a landslide. It is something else entirely: millipedes, in the millions.

Millions of Parafontaria laminata armigera crawl out to search for food and a place to breed. They often cross railway tracks along the way. Any driver unlucky enough to hit this stretch faces a wriggling carpet of millipedes. Each one is barely 3 cm long. Together they can carpet the tracks for up to 200 meters, and the crushed millipedes make the rails too slippery for trains to run safely, so the schedule is delayed by hours.

It took scientists fifty years to figure out this phenomenon. The millipedes’ life cycle explains it. They develop underground for seven years, growing from egg to adult. On the eighth year they surface, lay eggs and then die, restarting the cycle.

It’s nature’s own timetable. The trains just have to work around it.

P.S. Technology still bows to nature.

NPS GC and India’s BULK MRO are set to develop cooperation in the production of railway automation systems.

The two companies signed a memorandum at the Innoprom.India exhibition. It was signed by Dmitry Bolotsky, Deputy CEO for Commerce at NPS Group, and Davang Shah, CEO of the diversified industrial group BULK MRO.
The parties will work on localizing the production of railway automation and telemechanics systems for the Indian market.

NPS representatives also conducted negotiations with the leadership of the National Highways Authority of India (NHAI) and India’s Ministry of Railways, outlining next steps toward expanding the use of Russian train traffic management technology on local rail lines.

P.S. Russian tech for Indian rails.

An airport runway isn’t just concrete but a complex, layered structure built to withstand multi-ton airliners slamming down on landing. Here’s what makes up this “layer cake.”

😊Base. On weak, waterlogged or frost-prone soil, geosynthetics like geotextiles or geogrids separate the layers, keep them from mixing, and drain water away.

😊Drainage layer. Cushion of sand, crushed stone and sand-gravel mix that works as both drainage and shock absorber, dampening vibration and spreading the load.

😊Lean concrete. A low-grade rough layer laid over the drainage to level the surface and create an even platform for what comes next.

😊 Main surface. The key layer, taking on the impact of landing, repeated dynamic loads, temperature swings and moisture. Often laid in two stages: a lower-grade concrete first, then a high-strength, premium top layer.

😊 Finishing. The surface is brushed to create artificial roughness so wheels don’t slip, then coated with a film-forming liquid that slows water evaporation and prevents the concrete from cracking.

Total runway thickness can reach two meters, several times that of a regular road, and every layer is an engineering decision built on decades of calculation and use.

P.S. Two meters of calculation under the landing gear.

The Tejo Power Station, built in an Art Nouveau and Classicist style, supplied Lisbon with electricity for almost half a century. By 1975 the plant could no longer keep up with the city’s growing demands. This raised an important question: how to preserve and reimagine a building considered one of Portugal’s finest examples of industrial architecture? The answer came in 1990, when the Electricity Museum opened here, making use of the station’s entire space.

The museum is divided into two main parts. The first introduces visitors to the history of the power station itself. Here you can see the preserved machine halls and original equipment. The second part is devoted to the broader development of energy. Many of the exhibits are interactive, letting visitors get hands-on experience with how electricity is generated. The museum also regularly hosts themed exhibitions and conferences.

For a former power plant, this turned out to be a winning solution. The museum is popular with both locals and tourists, especially families with children.

P.S. Plant retired, museum powered up.

Mapping snake habitats in Goa, herpetologists found an anomaly.
King cobras should stick to the eastern part of the state: humid forests, overgrown floodplains, plenty of rodents to hunt. Yet the reptiles kept turning up in places entirely unsuited to them.

The researchers’ model pointed to railway stations as the magnets for these traveling snakes. The likely explanation is simple. Looking for shelter or food, cobras slip into train cars and end up hundreds of kilometers from home.

Reports back this up: up to three sightings of a snake aboard an Indian train every month. Neither side enjoys the company, so such stowaways are best reported to the authorities, who catch them and return them home.

P.S. Cobras get around on the railway schedule

A book and a train are a perfect pair, with one catch: once you arrive, you have to get off, even mid-chapter. The Japanese city of Higashimurayama solved that problem by building a whole library right into a train car. You can’t actually go anywhere on it, but you can still travel through worlds of knowledge and imagination.

Local residents built the “Reading Car” themselves in 1967, back when the town had no municipal library, social media was still half a century away, and books were one of the main forms of entertainment. The local railway company donated a decommissioned Seibu 101 series train car, which residents restored, fitting it out with bookshelves and a reading area. Today it holds around 5,000 books, mostly children’s titles, with the collection refreshed every year.

The library’s standout feature is the actual driver’s cab. Restorers kept some of the original controls intact, and kids are free to touch the buttons and levers, an instant hit with young readers.

P.S. Off the rails, into the stories.

The foundation of HSR bridge and overpass spans are massive concrete beams. The largest weigh 700 tons each, and moving one requires special heavy machinery.

A gantry crane on rubber tires carries the beams from the storage yard to the loading point onto a transport cart. The giant moves slowly — just 15 meters per minute — but with serious power: it can lift up to 900 tons of cargo.

Cranes like this are being installed at each of the 10 sites where concrete structures for the bridges and overpasses of Russia’s first high-speed rail line, Moscow–St. Petersburg, will be produced. Assembling a single unit takes about a month.

P.S. Heavy lifting for high speed
