The consolidations are much morepowerful than any previously used on thePere Marquette road, ami are among themost powerful locomotives of their typeconstructed by the builders. They carry duction of moderate weight Pacific typelocomotives using highly superheatedsteam. The superheater locomotives savean average of 22 per cent, in fuel as com-pared with Pacific type locomotives usingsaturated steam in the same service.

Among the new features presentedin the two designs which have beenwidely introduced on recent locomotiveswill be noticed the so-called outside steampipes, self-centering design of valve stemcrosshead guide, the self-centering guidefor the piston rod extension and the out- a working pressure of 180 pounds andhave 25 in. by 30 in. cylinders. The maxi-mum tractive power is 50,300 pounds. Theuse of a low steam pressure has con-siderably reduced the boiler work as com-pared with other locomotives on the roadcarrying 200 pounds pressure.
