As the weight on drivers is 388,000 lb., thefactor of adhesion is when working simple and is working compound. The driving wheels are 50 diameter and the boiler pressure 220 lb. These locomo-tives are capable of handling a freight train of 600 longtons at a speed of 5 , or 500 tons at a speed of Two Mallets are required to handle a train whichis hauled on the level by one Mikado. As a matter of comparison it is of interest to note thatthe U. S. R. A. hea\->- Mallet locomotives of the 2-8-8-2type weighed 531,000 lb. of which 478,000 lb. were on thedrivers. The rated tractive force was 121,600
