These bolts are % in. in diameter and are applied with two lock washers, oneunder the bolt head and the other imder the nut. Brake shoes are applied to the end wheels only and areoutside hung. The wheels are 53 in. in diameter and the wheel baseis 8 ft. 4 in.

The running gear is, therefore, quite flexible and, be-rause of the equalization used, the load on each is maintained nearly uniform. A Toil of Coal Never Went So Far Before Class I railroads in 1925 operated their freight trainswith the greatest efficiency in the use of fuel on record,according to a tabulation of reports just filed by the car-riers with the Interstate Commerce Commission and madepublic liy the Liureau of Railway Economics. An averagelit 159 pounds of fuel was required in 1925 to haul onethousand tons of freight and equipment, excluding loco-motive and tender, a distance of one mile. The averagefor 1925 was a decrease of 11 pounds imder t
