The Journey
Navigate from Almaty-2 (Almaty-2 station, Almaty, Kazakhstan) to Astana Nurly Zhol (Nurly Zhol station, Astana, Kazakhstan) across a span of 1440km. This is an overnight service.
Scenery Highlights
Tien Shan Mountain Foothills south of Almaty — first 1–2 hours from Almaty-2
Ili river depression and Kapchagay reservoir — agricultural belt transition
Lake Balkhash northern shore glimpses (weather dependent, ~700 km mark)
Endless Kazakh Steppes (Sary-Arka) — the bulk of the 1,440 km corridor
Karaganda industrial belt — coal-mining and steel works visible on approach to Karaganda
Ishim river lowlands — agricultural steppe around Astana
Spring tulips and feather grass across central Kazakhstan (May)
Golden steppe in September–October (best photography season)
Quick Facts
Duration
14.5 hours
Distance
1440 km
Est. Price
Budget to Mid-Range — from KZT 4,938 economy, KZT 10,393 business class, KZT 16,500–22,000 Grand Class (June 2026); KTZ flexible fare system offers up to 35% early-booking discount
KTZ KZ4A electric locomotive (push-pull configuration, 2 traction units per trainset); 25 kV AC overhead electrification
Locomotive Weight
KTZ KZ4A ~135 tonnes per unit; full trainset with 2 traction units + 20 passenger cars approximately 800 tonnes
Track Gauge
1,520 mm (Russian broad gauge)
Braking Technology
Talgo pneumatic brakes with passive tilting system; regenerative braking via KZ4A traction units on electrified sections
Route Engineering Challenges
Extreme temperature variation between summer (+45°C) and winter (-50°C) — Talgo 250 climate-rated for the full range, unique among 1,520 mm broad-gauge passenger services
Long 1,440 km corridor across open steppe requires reliable climate control and dust filtration — open-steppe dust infiltration is a recurring rider complaint
Broad gauge 1,520 mm requiring Talgo variable-gauge axle technology (though the Kazakh fleet is fixed-gauge; variable-gauge is for international services in Europe)
Talgo passive tilting system allows higher speeds on existing curves without infrastructure modification — 130 km/h certified on 1,520 mm Soviet-era infrastructure
Steppe blizzards (buran) in January–February can delay services by 1–3 hours — trainsets are climate-rated but steppe snow drifts occasionally close the route
Sparse cell-tower coverage between Karaganda and Astana (~600 km gap) limits Wi-Fi continuity — satellite backhaul is the only practical solution
Tien Shan foothills south of Almaty require slow speed approach (~50 km/h) for the first 80 km — engineering constraint of the post-Soviet track geometry
Model
Talgo 250 (assembled in Kazakhstan by Talgo-KTZ joint venture at the Astana LKZ plant from 2019)
Max Speed
130 km/h certified in Kazakhstan (250 km/h design maximum)
Configuration
Double-decker push-pull trainset; twin electric traction units (KTZ KZ4A) at each end
Temperature Range
Operating range −50°C to +45°C for Kazakh climate extremes
Bodyshell
Wide 2,980 mm bodyshell optimised for Russian 1,520 mm loading gauge
Tilting
Talgo passive tilting enables faster curve running without infrastructure upgrade
Carriages
2 Grand (10 places each, private bathroom/WC), 2 Business (10 places each), 16 Tourist (20 places each) = ~480 passengers per trainset
Russian/Kazakh onboard announcements; English/Kazakh/Russian on tickets.kz booking platform
