Uzbekistan's Heatwave Pushed Rails Past 55°C, and the Country's Emergency Playbook Began in Real Time

The figure that mattered was 55. Not the air temperature, which climbed past 46°C across southern Uzbekistan and as high as 49°C in the desert regions between 18 and 19 July — not the 48°C that ended up on the front pages — but the temperature of the steel rails on Tashkent's elevated metro line, which breached the safety threshold written into the system's operating rules and forced the country's transit operator to slow its trains in the middle of a working week ²⁴⁵.

That detail, more than any thermometer reading, captures how a climate event turned into an operational emergency across Uzbekistan in mid-July 2026. The state enterprise Toshkent Metro announced on 14 July that train speeds on the overground sections would be temporarily reduced starting the next day, citing air temperatures that pushed elevated rail temperatures above the 55°C limit ²⁴. The specific speed figures cited in some reporting — a cut from 60 km/h to 40 km/h — are not stated in the operator's published accounts, and HeyDay could not independently verify the exact numbers ²⁴.

By the time the temperature peaked on the weekend of 18–19 July, the response had spread far beyond the capital. State kindergartens were already suspending operations in Khorezm and parts of Karakalpakstan, and three more regions followed in the days that followed ⁸¹¹. Heavy-vehicle traffic was restricted during the hottest hours in at least one southern region, water was sprayed on major roads in the capital, and fire and rescue teams were deployed round-the-clock near markets and crowded areas to respond to heat-related emergencies ³⁷.

The headline figure of 48°C is consistent with the southern and desert range reported across outlets. Gazeta.uz, drawing on its own reporting, recorded 43–45°C across much of the country and 46–49°C in southern and desert regions, with several all-time records broken during the 18–19 July peak ⁵. Other international outlets reported 42–45°C widely and 46–48°C in the south ⁶⁷⁹. No single nationwide high was published; the sources simply disagree on the precise regional maximums.

Tashkent's metro is a modest system by global standards, but a meaningful slice of the city's working population depends on it, and the elevated sections run through open air where the rails absorb the sun directly. The operator's 14 July announcement framed the speed restriction as a precaution tied to a specific number: rail surface temperatures above 55°C, the limit written into existing operating regulations ². The slow-down took effect 15 July and was reported across the region ²⁴.

The choice of 55°C is not arbitrary. Steel rails expand as they heat; past a certain point, the risk of buckling — the so-called "sun kink" that has disrupted railways from Britain to the American Midwest — rises sharply, and operators worldwide respond by slowing or suspending service. Uzbekistan is not the first country to do so, but it is unusual to see a Central Asian metro operator invoke that limit so publicly, and in the middle of a heatwave that was already breaking temperature records in the same country.

The reporting file makes a useful distinction the video narration did not. Three specific claims made on camera are not borne out by the underlying sources: the exact "60 to 40 km/h" metro figures, the named regions of Navoi and Tashkent for kindergarten closures, and the detail about fountains switched to continuous operation. HeyDay's reporting treats those three as unverified.

What the sources do support: an elevated-rail temperature threshold of 55°C and a 14 July announcement effective 15 July ²⁴; a 46–49°C southern peak on 18–19 July with multiple all-time records broken ⁵; kindergarten suspensions in Khorezm, parts of Karakalpakstan, and three further regions (including Jizzakh) on 14–17 July ⁸¹¹; heavy-vehicle restrictions and road-water spraying during the worst of the heat ³⁷; and round-the-clock fire and rescue duty near markets and crowded areas ³⁷.

The clearest pattern in the reporting is that Uzbekistan's response unfolded region by region, in roughly the order the heat arrived, rather than as a single nationwide declaration. Khorezm and Karakalpakstan moved first because they sit in the northwest, where the heat arrived earliest; the capital's metro moved next, on a regulatory threshold that left the operator little choice; and the fire and rescue rotations followed the markets and crowded zones, where the human risk concentrated.

There is no single named official quoted across the reporting. The statements on the record are institutional: Toshkent Metro's press service on the rail threshold, and the regional Departments of Preschool and School Education in Khorezm and Jizzakh on the kindergarten suspensions ²⁸¹¹. That is itself part of the story — a heatwave handled through press releases and departmental notices, not through a single emergency declaration, because no single instrument exists to declare one.

For now, the reporting is operational rather than political. No casualty figures have been published, no central emergency declaration has been issued, and the official line is that the measures are temporary and proportionate to the heat. The harder questions — what this heatwave cost in lives, productivity and infrastructure, and what comes next — will only become visible in the weeks that follow.
