Baldwin [Illustration: Uncaptioned locomotive.] Altogether, perhaps a quarter of a million steam locomotives have been built in America. From the first they have been objects of interest to young and old. They have been depicted and photographed untold times, and as a result a wonderfully accurate pictorial record of their construction and appearance has been built up. The locomotives themselves, however, as they wore out or fell into disuse were usually destroyed for the value of their scrap metal. This process has been greatly hastened in recent years by the trend toward the use of diesel-electric and other types of motive power. Few remain of the busy multitudes of steam locomotives that served so well in building the Nations on this continent. The picturesque and once popular steamer has today become the vanishing iron horse. It is proposed to deal here only with the relics and replicas of the historic steam locomotives used during the pioneer days of railroading on this continent, in the period 1825-1849. Of these, only 11 have survived in even reasonably complete form. With the remaining parts of several others, they are accounted museum treasures. Full sized operable replicas of 7 other famous early locomotives have been constructed. All these together afford a good idea of the actual construction of the locomotives of long ago. Not to be included, are the many nonoperable, wooden facsimiles of early locomotives that merely serve to show the general external appearance of the originals they represent. Many such are to be seen in the railroad collection in the Baltimore and Ohio Transportation Museum located at the old Mount Clare station and roundhouse at Baltimore, Md.
