So pleased was the Philadelphia and Reading with this locomotive that the road decided to order more of the same general style. However, as Eastwick and Harrison shortly became involved with plans to construct locomotives in Russia, and contemplated closing their Philadelphia works, most of these additional locomotives were made by other builders. A dozen or so, somewhat similar to the _Gowan and Marx_, were built in the machine shop of a Lowell, Mass., firm named “Proprietors of Locks and Canals on Merrimack River.” Others were built by the New Castle Manufacturing Co. at New Castle, Del. At least two, however, the _Boston_ and the _J. E. Thayer_, were built by Eastwick and Harrison, and placed in service on the Philadelphia and Reading in September and October, respectively, of 1842. What is thought to be one of these now famous locomotives has survived (figure 56). It is the earliest extant 4-4-0, or American type. Known today as the _Peoples’ Railway No. 3_, it was obtained at fourth or fifth hand in about 1872 by the Peoples’ Railway, which was then establishing a line from the York Street station at Pottsville to Minersville, Pa., a distance of about 4½ miles. Seldom used by the Peoples’ Railway after 1883, it was obtained by the Reading Co. in the early 1920’s when that road took over some of the rolling stock of the Peoples’ Railway. Since October 1933 it has been on loan to The Franklin Institute in Philadelphia, where it is exhibited with the Braithwaite-built _Rocket_ of 1838, also owned by the Reading Co. The _No. 3_ has been the subject of much speculation and investigation since it was obtained by the Reading. Its origin and the name of its builder are not definitely known, nor is it absolutely certain for whom it was constructed. Without question, however, it is of the period of the early 1840’s, and is similar in appearance to the famous _Gowan and Marx_, although of considerably longer wheelbase. Paul T. Warner, for many years writer and historian for the Baldwin Locomotive Works, conducted an intensive examination of the _No. 3_, and in January 1934 prepared a thorough paper on his findings, based on a careful comparison of the _No. 3_ with contemporary drawings of the various other locomotives, and on a comparison of its dimensions with those still known of the others. He concluded that from the information at hand it was not possible to state positively which, if any, of these locomotives it was, or even if it had been built for the Philadelphia and Reading. Similar engines, he pointed out, had also been built by Eastwick and Harrison for other railroads in eastern Pennsylvania, among them the Beaver Meadow Rail Road and Coal Co. and the Hazelton (sic) and Lehigh Rail Road. The _No. 3_ could easily have been built for one of these roads before falling into the possession of the Peoples’ Railway, particularly since it is known to have had a number of prior owners.
