The heavy stationary engine has quarter boxes inwhich the bearing entirel encircles the journal and thebrasses are adjustable in all for wear, while mod-ern locomotives must get along ^vith the half-shell non-adjustable boxes of seventy-nve y ■ars ago.

Long THE Philadelphia & Reading has recently receivedfrom The Baldwin Locomotive Works a number o;Consolidation type locomotives which are notable fortheir weight and hauling capacity, and also because they arethe only engines built to a railroad companys design to beincluded in the Railroad Administration orders last year.
