"The aluminum BethGon® II has been designed to transport coal with unrivaled efficiency. It has a 42,000 pound lightweight which allows for a hefty 244,000 pound payload. The BethGon's® patented double tub floor design utilizes coal carrying capacity like no other gondola. Its innovative longitudinal tub floor design carries an extra 36,000 pounds of coal when compared to traditional gondola designs. It also lowers the BethGon's® center of gravity for a more stable ride, reduced wear, and lower maintenance costs."
