Decarbonizing heavy rail sounds easy until you actually look at a map. Electrify the line and you need catenary wires, substations, and decades of permitting. Go hydrogen and you need refueling depots every few hundred kilometers. Go battery and you need charging infrastructure plus a route short enough that the loco doesn’t run out halfway through a coal haul.<\/p>\n
Each option locks you into one kind of corridor, one kind of fuel, one kind of customer. So most operators in emerging mining markets just keep running diesel, because at least diesel doesn’t ask them to rebuild the railway first.<\/p>\n
CRRC’s answer, unveiled this week in Urumqi, is to stop choosing. The Chinese state-owned rolling stock giant rolled out a new locomotive platform branded XUANKUN, marketed internationally as VELFORCE, that comes in three flavors on the same chassis: a pure battery loco, a hydrogen fuel cell loco, or a diesel-battery hybrid. One body, one cab, one set of bogies, three completely different propulsion systems depending on what the customer needs and what the line can actually support.<\/p>\n
The launch happened at the 9th China-Eurasia Expo in Urumqi, capital of Xinjiang, where CRRC’s booth ran a sand-table display of more than 30 pieces of new-energy rail equipment. According to Xinhua’s coverage of the expo<\/a>, the VELFORCE series offers three power options: hybrid, pure battery, and hydrogen fuel cell. The whole thing is pitched at export markets in Central Asia, where the mining sector still runs on aging diesel and the grid is too patchy to electrify every freight corridor.<\/p>\n The naming is doing some work here. CRRC’s official announcement<\/a> says the Xuankun name, the second addition to the company’s “Xuan” product family, draws from the Kunlun Mountains, a range spanning the China\u2013Central Asia border, evoking rock-solid engineering and clean-energy reliability. If you don’t speak corporate branding: this thing is aimed squarely at the harsh-climate mining and port railways of Central Asia.<\/p>\n Power-wise, the series covers 1,000kW to 2,000kW across the three powertrains. That’s roughly 1,340 to 2,680 horsepower per unit, which is industrial-rail territory: heavy haul on mine spurs, port shunters, ore lines, coal hoppers. Not the stuff you see pulling passenger expresses, but the stuff that quietly burns more diesel per mile than almost anything else on rails.<\/p>\n “Modular platform” is one of those phrases that gets thrown around so loosely it usually means nothing. In this case it has a specific consequence. An operator running a mine railway in Kazakhstan can spec a hydrogen variant for a long haul to a port, then order a battery variant for short-distance yard work, and the spare parts, maintenance procedures, driver training, and depot tooling all carry over.<\/p>\n CRRC says the platform offers modular configurations to match diverse operator requirements, designed for the harsh climates and rugged haulage demands of Central Asian mining and port railways.<\/p>\n This isn’t theoretical for CRRC. The company has been iterating toward this for years. In June 2023, CRRC rolled its “Ningdong” off the line in Datong, the first Chinese hydrogen locomotive converted from a diesel, and at the time the most powerful hydrogen-powered locomotive in the world.<\/p>\n CRRC’s own writeup<\/a> of a later milestone covers the next step: in March 2024, a high-power hydrogen shunter developed with China Energy hauled 105 C80 freight cars, a 10,000-tonne load, for two kilometers at constant speed at Sidaoliu Station on the Xinshuo Railway’s Bazhun Line. Those were one-off demonstrators. VELFORCE takes the lessons and bakes them into a serialized product line with a brand name and a sales pipeline attached.<\/p>\n CRRC’s numbers on the environmental case are aggressive but worth flagging carefully. The company says hybrid units cut annual emissions by 4 tonnes of pollutants and 374 tonnes of CO\u2082, which it frames as equivalent to planting 34,000 trees, while the battery and hydrogen variants achieve zero emissions. That “zero emissions” claim is tailpipe-only. Well-to-wheel depends entirely on where the electricity and hydrogen come from, and a lot of Central Asian power still leans heavily on coal and gas. Worth keeping in mind whenever a state-owned manufacturer drops a press release with a tree-counting metaphor in it.<\/p>\n A staffer at the booth, Li Rongkang, gave Xinhua more granular numbers. He said the hybrid model cuts nitrogen oxides, hydrocarbons, and carbon monoxide emissions by 45 percent, 73 percent, and 83 percent respectively compared with traditional locomotives, and that each unit saves more than 370 tonnes of carbon dioxide a year.<\/p>\n Those are the kind of percentages that matter for mine operators answering to provincial air-quality regulators, which in China, and increasingly in Kazakhstan, is not a small thing.<\/p>\n CRRC is selling VELFORCE on what it calls five integrated strengths: safety, green performance, efficiency, intelligence, and economy. The safety part is the most concrete. The company describes a fail-safe architecture with dual-level vehicle and component protection, real-time monitoring, and automatic emergency braking.<\/p>\n Hydrogen rail equipment has always had to fight a perception problem, since high-pressure tanks in a confined cab make customers nervous, fairly or not, so the dual-redundancy spec is aimed straight at the procurement officers who have to sign off on something more flammable than diesel.<\/p>\n The “intelligence” piece is mostly fleet telematics and predictive maintenance, plus the usual list of AI voice control, one-button departure, obstacle avoidance, and precision docking, which is table stakes now for any serious rolling stock vendor. The “economy” piece is where this gets interesting commercially. One chassis means one production line, which means lower unit cost than building three separate locomotive families. That’s CRRC’s structural advantage over Alstom or Siemens trying to compete on hydrogen rail in emerging markets.<\/p>\n The launch site isn’t accidental. Alongside VELFORCE, CRRC showcased its benchmark export locomotive for Uzbekistan, a key Central Asian rail project, plus Lijiang tourist trams, maglev systems, double-deck container flatcars, KM98 heavy-haul coal hopper cars, and new-energy X12 buses.<\/p>\n The China-Eurasia Expo is essentially a Belt and Road trade show, and Central Asian mining countries are exactly the kind of customer that can’t afford full electrification but wants out of diesel for both cost and air-quality reasons. It’s the same off-grid logic showing up elsewhere in the hydrogen world, from Hyundai’s plan to run South Korea’s Antarctic bases on green hydrogen<\/a> instead of diesel to industrial plants wiring hydrogen straight into the grid.<\/p>\n Tian Jun, chief engineer of China’s National Railway Administration, gave the regulatory blessing at the unveiling, noting the platform’s adaptability to varied scenarios and confirming its alignment with green rail evolution across Eurasian corridors.<\/p>\n CRRC General Manager Wang Feng framed the Xuankun launch as a new starting point for systematic, branded, and internationalized development of new-energy locomotives. Reading between the corporate lines: this is the platform CRRC plans to take global, not just keep at home.<\/p>\n The interesting thing about VELFORCE isn’t any single spec. It’s the bet on where the variable should live. For two decades the rail industry assumed decarbonizing freight meant choosing between three expensive infrastructure builds, wires, hydrogen pipelines, or charging, and committing entire corridors to one of them.<\/p>\nWhat “modular” actually buys an operator<\/h2>\n
