The boilers of all the new engines have radial stay fireboxesand all the locomotives for road service are equipped withSchmidt superheaters. The reversion in this order, to the2-10-2 type locomotive for heavy freiglit service is a matter ofconsiderable interest, indicating, as it does, the success achievedby the former engines of this type. The retention of the bal-anced compound in heavy duty passenger service is also note-worthy. These locomotives are among the most highly devel-oped thus far built, and their successful performance can safelybe assured.
