Thus the gross weight per foot of length for the120-ton cars is per cent greater than for the 5 5-tongondola, and per cent greater than for the hopper. Fora given length of train the net tonnage that can be handledin the larger cars is even greater. It has been found entirely practical to handle trains of 7 3% of Bofsfec j ./• ~S* -f ~S* -S* ~J»
