"The investment required using technology that significantly shortened thawing time of railcars. Difficulties in unloading railcars and coal delivery pile-ups have been eliminated. The process ensured the effective use of thermal energy for thawing process through monitoring and automation of the technological process. The project was performed in a strictly specified time frame."
