Germany: The leasing company manufactured the prototype at its own Waggonbau Graaff factory in Elze, Germany. Previously, the same site produced a tank wagon for transporting ammonia and all types of LNG.
The tank volume of the type G92.062D Zagns unit is stated as 62 m³, with a payload capacity of 61.7 t and an overall length over buffers of 14.4 m. The running gear features two two-axle bogies, each with an axle load of 22.5 tf. This design allows the wagon to negotiate curves with a minimum radius of 35 m.

VTG notes that the tank is constructed from P460 carbon steel. Rigid polyurethane foam insulation of 200 mm thickness provides an operating temperature range from -40 °C to +50 °C. Loading and unloading of liquefied and gaseous CO₂ is carried out via a hydraulic valve. Cryogenic equipment maintains the carbon dioxide in a liquefied state during transport.
The transported liquefied and solid CO₂ can be used in petrochemical, food, and pharmaceutical industries. Furthermore, the practice of capturing carbon dioxide at industrial facilities is expanding, allowing for its subsequent transport and disposal in specialised sites to meet carbon emission reduction targets.
