UNIT TRAIN COAL CAR DESIGN CONSIDERATIONS
Unit Coal Train cars in high mileage, heavy train service have shown weaknesses in almost all areas of design because of the radical increase in severity of service. Careful inspection and evaluation of these cars on a periodic basis will reveal design and component selection changes that must be made on future cars. The overall economics of the 100-ton cars and its effect on track must be faced soon to reduce transportation costs. This paper discusses many of the design problem areas and suggests state of the art solutions for improvement.
