This book is a general overview of steam and diesel locomotive terminal facilities on American railroads, concentrating on the lake steam and early diesel era 1930s-1950s. It shows roundhouses, coaling, sanding, and water stations, ready tracks, washers, cinder plants, and other facilities needed to service steam locomotives, many of which were later converted for diesel use. This book is the second in a series of small books that we are publishing about railroad facilities, following Steam Locomotive Coaling Stations and Diesel Locomotive Fueling Facilities, published in 2002. The present work concentrates on the locomotive terminal that was found in most railroad yards and at division points. It is not exhaustive in treatments by any means; at best it is a representative sampling, because the variety of these facilities is huge.
