One-quarter of railway tracks constructed in Astana
LRT Construction in Astana: A Progress Update and Insights into the Innovative Rail Fixing System
The construction of Astana's LRT (Light Rail Transit) is cruising along, boasting a 25% completion rate, with a substantial 5.6 km of the 22.4 km double-track line already laid. Liter.kz provides this exciting update.
CTS, the transportation company overseeing the project, has introduced specialized tools to the construction site, including a shunting locomotive, a rail excavator, a concrete mixer with a pump, a jib crane, and platforms.
The innovative DTVII2-1 rail fixing system, known for its advantages in noise reduction, high durability, and adaptability to various conditions, is being employed in the project's development. The system offers a noise reduction of up to 5-10 dB compared to traditional methods, ensuring a quieter ride for passengers and reduced disturbance for nearby residents.
Last year, the initial 500 meters of track were launched on the overpass segment connecting stations No. 116 and 117. This experimental phase was instrumental in evaluating the impact of winter weather conditions on the track structure's condition.

In an unexpected twist, witnesses recently spotted an incredible waterfall near the "Abu Dhabi Plaza" shopping center in Astana. However, it turns out the water cascading from the LRT tracks formed a fascinating, albeit temporary, waterfall spectacle.
The DTVII2-1 Rail Fixing System: An In-Depth Look
The DTVII2-1 rail fixing system, employed in Astana's LRT project, provides several key features, including:
- Vibration Damping: Utilizing elastomeric pads or composite materials, it minimizes noise and vibration levels.
- Adjustability: Allowing vertical and horizontal alignment contributes to precise track geometry, which ensures stability and safety.
- Durability: Corrosion-resistant materials such as stainless steel or epoxy-coated components enable the system to withstand harsh climates.
- Modular Design: A modular design enables fast installation and maintenance for efficiency.
- Load Distribution: Evenly distributes the dynamic loads from trains to the concrete slab or ballast, enhancing track lifespan.
- Insulation: Electrically isolates rails to prevent stray currents, protecting infrastructure from corrosion.
The system offers numerous benefits for Astana's LRT:
- Climate Resilience: The system demonstrates resistance to extremes in temperature (ranging from -40°C winters to +40°C summers) typical in Kazakhstan.
- Speed of Installation: Reducing construction timelines is a significant advantage for high-traffic urban areas like Astana's LRT.
- Low Maintenance: The long service life translates into reduced lifecycle costs, ideal for public transit systems.
- Safety Compliance: Maintains compliance with international standards for rail fastening in light rail projects.
- Noise Reduction: An essential feature for Astana's urban zones, ensuring minimal disruption to residents and businesses.
Typical use cases for the DTVII2-1 rail fixing system include light rail systems and tunnels/bridges where vibration control and stability are crucial.
While the "DTVII2-1" designation might not be universally standardized, alternative systems such as Pandrol FASTCLIP or Vossloh W-Spring maintain similar features. For detailed specifications, please refer to project documentation or collaborate with suppliers like NICHIHA, Voestalpine, or local contractors.
- The DTVII2-1 rail fixing system, currently being used in Astana's LRT project, has demonstrated its potential in the transportation industry, particularly in sectors like light rail systems and tunnels/bridges, owing to its vibration control and stability.
- The innovative DTVII2-1 rail fixing system, known for its advantages in noise reduction, high durability, and adaptability to various conditions, is a significant asset in Astana's LRT development, as it ensures a quieter ride for passengers and reduces disturbance for nearby residents.
