HVK has received a certificate from the FBU "RS FZHT" for a six-axle articulated tank wagon type 15-629 for transportation of light oil products. This is the sixth multi-axle certified model in the company's portfolio, designed for the 1520 mm track gauge. It is capable of carrying up to 108 tons of light oil products with a capacity of 160 cubic meters. The wagon consists of two sections connected by an articulated joint unit. Unlike usual wagons, where the tank needs to be filled with 15% underload, 15-629 uses 100% of tank volume, which provides savings on transportation of goods.
