Ten years ago, fewer than five trains a day rolled out of China toward Europe. Today, more than 55 depart every 24 hours. The Iron Silk Road has quietly redrawn the trade map of the entire Eurasian continent.
From Barren Platforms to Tens of Thousands of Trains
In June 2016, the China-Europe Railway Express unified its brand and officially launched. The first batch of trains departed simultaneously from eight cities — Chongqing, Chengdu, Zhengzhou, Wuhan, and Yiwu among them. That year, a grand total of 1,702 trains hit the rails, averaging fewer than five a day.
Ten years on, the picture is completely different. According to data released by the China State Railway Group on June 19, annual traffic reached 20,022 trains in 2025 — a 10.8-fold increase over a decade, at an average annual growth rate of 31.5%.
By June 10, 2026, the Express had already surpassed 10,000 trains and one million TEUs for the year-to-date period, setting a new historical high for the same period.
On June 22, the whistle sounded at Chongqing's Tuanjiecun Central Station. Train X8013 of the China-Europe Railway Express (Chengdu-Chongqing) — fully loaded with 182 "Made in Chongqing" vehicles — set off for Russia's Vorsino station. The first time an entire train used the new 40-foot, 35-ton general-purpose car containers, sized precisely to fit the railway clearance limits of major countries along the route, enabling seamless integration with rail, road, and maritime transport.
"Made in Chongqing" Cars Reach Europe in Two Weeks
This railway line means far more to China's manufacturing sector than a logistics channel. For Chongqing's auto exporters, the old route forced goods down the Yangtze River to eastern coastal ports — a lengthy and costly detour. The Express cuts that journey to an average of two weeks, delivering cargo straight to the European hinterland.
Yu Qinghua, general manager of overseas marketing for Deepal — the new-energy vehicle brand under Changan Automobile — revealed that the Express provides priority marshaling, shipping, and guaranteed space for new-energy vehicles. Thanks to those advantages, Deepal's overseas orders hit 13,500 units in the first quarter of this year, up 85.4% year-on-year.
The variety of freight has changed beyond recognition. When the service launched in 2016, it primarily carried mobile phones and computers. Today, freight categories have expanded to 53 sectors and over 50,000 types of goods — clothing, footwear, automobile parts, grain, wine, coffee beans, and timber among them.
Total cargo value reached US$67.7 billion (approximately HK$527 billion) in 2025. The Express has become the fast track for "Made in China" products going overseas, and for European agricultural products and chemical raw materials entering China.
Three Maritime Crises, Three Times Stepping Up
Three separate maritime crises have exposed the true strategic value of this steel corridor. In 2021, the Ever Given ran aground in the Suez Canal, briefly paralyzing global shipping and triggering a surge of Express orders. When the Red Sea crisis erupted in 2023, sustained Houthi attacks on commercial vessels pushed European buyers toward land transport.
Then in 2026, Iran's blockade of the Strait of Hormuz during the US-Iran war placed renewed pressure on global energy shipping. Each time, the Express's "all-weather, blockade-proof" characteristics drove the international shipping industry to a deeper recognition of its value as a strategic backup.
Make no mistake: this is no coincidence. It is the result of Beijing's systematic planning over two decades.
A Network Spreading Across Eurasia
Today, 129 cities in China have opened routes for the China-Europe Railway Express, reaching 236 cities in 26 European countries. At the Khorgos railway port in Xinjiang, annual train traffic to Europe and Central Asia skyrocketed from fewer than 400 in 2016 to 9,882 in 2025.
After Urumqi Customs and State Railway jointly implemented the "smart railway port plus local rapid customs clearance" reform, port clearance time for imported goods dropped from two to three days to under 16 hours — a 70% reduction. Processing time for exported goods shrank from six hours to just one hour, an 80% decrease.
Routes connecting Central Asia are expanding, too. In Zhengzhou, a train loaded with 1,700 tons of textiles recently departed for Hairatan, Afghanistan. In Xi'an, the first dedicated rapeseed oil train from Krasnoyarsk arrived on May 2. Sixty-two containers carrying over 1,500 tons of Russian rapeseed oil completed the cross-border direct run in 11 days. Unloading and warehousing took just 1.5 hours — nearly half the time required under traditional models.
Behind every single train lies a restructuring of the entire logistics order across the Eurasian continent. Whoever controls the land routes holds the leverage in the trade contests of the next era.

When the Russia-Ukraine war broke out, energy costs in Germany, a country heavily reliant on Russian natural gas, spun instantly out of control. Electricity prices at one point surged sevenfold, forcing ordinary people to dream up all manner of clever tricks to save on their power bills. One of those tricks has become a distinctive sight on German streets: the "balcony solar" system.
To cut power bills, Germans turned balconies into power plants.
"Balkonkraftwerk": Miracles On Balconies
This simple generating setup costs just a few hundred euros, yet more than 1.33 million units have been installed across Germany in three years. The German government has even amended the law, granting tenants with no rooftop of their own priority installation rights.
What Germans call the "Balkonkraftwerk", or "balcony power plant", is actually just one or two solar panels hung outside the railing, an inverter the size of a shoebox, and a plug that goes into a household socket. The current then flows back into the home: the inverter sets its output voltage slightly higher than the 230V household supply, so solar power feeds in reverse into the wiring. A small storage battery can be added to keep the power coming at night.
The "Balkonkraftwerk": railing-hung panels, a shoebox-sized inverter, one plug.
The principle is not complicated. It works rather like a water supply system. Pipes maintain a steady pressure; turn on the tap and the pressure difference pushes the water out. The grid works the same way. China's standard household voltage is 220V and Germany's is 230V. The inverter in a balcony photovoltaic module simply nudges its output voltage slightly above the socket voltage, pushing solar power back in.
Once the current enters the socket, it is consumed on the spot, "drunk up" by the appliances at home. Less electricity is drawn from the grid, and the meter turns more slowly. If no appliances are running, then in areas where bidirectional metering is permitted, the surplus power flows out of the home along the mains line and back into the grid.
A Few Hundred Euros, Real Money Back
A "balcony power plant" sells for roughly 200 to 500 euros, depending on output. The best-selling 800W model goes for about 350 euros. A solar-plus-storage package with a battery costs between 800 and 1,500 euros.
A granny who lives in Stuttgart finds a 300W system enough to cover her basic needs: lighting, the router and electric fans. She now checks the next day's sunshine forecast every evening. If the sun will be out, she schedules a bike charge or runs the dishwasher. "Save whatever you can," she says.
Granny's 300W system covers her lights, router and fans.
Her nightly ritual: the sunshine forecast. "Save whatever you can."
Weyland, a young man in the northern city of Kiel, hung two panels with a combined output of 600W on the balcony of his rented apartment. In good weather they cover half of his daily electricity use. The whole system cost under 500 euros, yet saves him more than 90 euros a year, a payback period of about five years. These days he spends his time glued to the app, watching the generation figures roll in.
Kiel renter Weyland's two balcony panels total 600W.
In southern Germany, where the sunshine is better, a standard 800W system generates about 750 to 850 kWh a year. At last year's average price of 0.39 euros per kWh, that puts up to 295 to 334 euros a year back in the user's pocket.
For an ordinary household consuming 3,000 kWh a year, saving is about 25 to 28 percent. A single-person household using around 1,500 kWh could ideally save 50 to 57 percent.
No Roof? No Problem
Europe used to put solar panels on rooftops. But more than half of Germany's population lives in rented housing, the highest share in the EU. That means no roof, no land, nowhere to put panels, and no eligibility for the complicated installation and grid-connection approval process.
No roof, no problem: balcony solar is the tenant's lifesaver.
That was when Chinese manufacturers stepped up, Anker Innovations, EcoFlow and Zendure among them. They launched lightweight, low-cost balcony solar kits that skip the tedious paperwork and are far easier to use.
Panels have been slimmed down from the traditional 20kg to just 3 to 5kg. Hook-style railing clamps fix them in place with a few screws. Some models can simply be lashed on with metal cable ties, and they can be taken down easily when moving.
Voltage has dropped from the 600V to 1,000V high-voltage direct current of rooftop solar to a safe 30V to 60V. The plug goes straight into an ordinary socket, and monitoring is done entirely through an app. Installation and use are virtually "zero-threshold". German young people love it. Chinese manufacturers have turned solar "engineering" into a consumer electronics product for everyone.
Berlin Gives the Green Light
The German government has also given the green light. A legislative amendment in May 2024 allows self-installation without prior approval; simple registration afterwards is enough. Balcony solar is now a "privileged installation", on par with disabled-access facilities and EV charging points. Landlords and owners' committees may not block installations on grounds such as "spoiling the view". A landlord who wants to refuse must prove a safety hazard; if the tenant can fix the hazard, the installation goes ahead anyway. The government also waived the 19 percent VAT, and cities including Berlin and Stuttgart have rolled out dedicated subsidies of up to 500 euros. All income from generation is exempt from personal income tax.
With the government "loosening the reins", balcony solar has grown rapidly. Around 260,000 units were added in 2023. The figure soared to 435,000 in 2024, and another 430,000 or so were registered in 2025. That is 1.1 million units installed at lightning speed in three years. By May this year, cumulative installations had reached 1.33 million, the equivalent of more than a thousand German households signing up every day.
Policy green light: install first, register afterwards.
Other European countries have followed suit. The Netherlands had reached 600,000 cumulative installations by the end of 2025, the highest penetration after Germany, with nearly 5 percent of households equipped. Austria has installed 250,000 units, Italy 200,000 and Belgium 150,000.
Made in China, Invisible at Home
Of the solar panels imported into Europe, 98 percent come from China, and 70 percent of micro-inverters are Chinese-supplied. In balcony energy storage, Chinese companies had already secured the first seven places of the top ten best-seller spots in Europe as early as the third quarter of 2024. Industry forecasts see global installed balcony solar capacity exceeding 50 gigawatts by 2030, with China likely to claim more than 40 percent of it.
Yet in China itself, these products are practically invisible in cities. For one thing, electricity in China is genuinely cheap. For another, China follows a "centralized plus distributed" path.
The northwest builds gigawatt-scale centralized solar bases across deserts and the Gobi on a massive scale, using ultra-high-voltage transmission to solve the geographic mismatch. The east develops distributed solar on factory and detached-house rooftops. Rural rooftops easily run to tens or even hundreds of square meters, accommodating 20kW to 50kW systems. That is dozens of times the generating capacity of balcony solar.
With no domestic demand to speak of, Chinese companies have nonetheless struck overseas demand with pinpoint precision and taken command of the global balcony solar market. The same story has played out with saddle-style window air conditioners, fully automatic lawnmowers, electric-assist bicycles and AI game-tracking cameras. To Western politicians, China's technological rise is a threat. But to ordinary people abroad, Chinese products have made life better, time and again.
