We thought you folks would be interested in this experimental locomotive and for that reason we give it a prominent place and much detail. Editor

Locomotive 60,000, the subject of the present publication, was designed and built by the Baldwin Locomotive Works as an experiment to ascertain the gain in efficiency by the use of high pressure steam and high ratios of expansion. Opportunity was also taken to try out certain novel details of construction.

Through the courtesy of the Pennsylvania Railroad the locomotive was submitted to an extensive program of tests on their locomotive test plant at Altoona (Pa.), and it was subsequently given road tests on this line and on a number of other prominent railroads.

DESIGN AND CONSTRUCTION

The locomotive forming the subject of this bulletin is the 60,000th locomotive built by The Baldwin Locomotive Works. It was built during the early part of the year 1926 as an experiment to ascertain the possible economies which can be effected by the use of high steam pressures and a high ratio of expansion.

Up to a certain period, development of locomotive design brought with it mainly an increase in, weight of individual locomotives, the increase in power being proportionate to the increase in weight. This increase in power made possible notable economies in railroading. Of late years, however, the demand for still further economies has led locomotive) designers to strive to increase the efficiency of the locomotive, and thus give increased power per unit of locomotive weight. Among the means adopted successfully to this end, are the use of superheated steam, various fuel and labor-saving devices, improved boiler design, more efficient steam distribution, and refinements in design and materials for locomotive parts.
