While there seems little question that these locomo- tives were not built as a direct order for the Cumber- land Valley Railroad, an article s appearing in the Railroad Advocate in 1855 credits their design to Smith. The article speaks of a 2-2-4 built for the Macon and Western Railroad and says in part: 1 his engine is designed and built very generally upon the ideas, embodied in some small tank engines designed by A. I'. Smith, Esq., for the Cumberland Valley road. Mr. Smith is a strong advocate of light engines, and his novel st\lc and proportions of engines, as built for him a few years since, by Seth Wilmarth, at Boston, arc known to some of our readers. Without knowing all the cir- s Railroad \dvocat, I >© ember 29, 1855), vol. 2, p. 3. cumstanccs under which these engines are worked on the Cumberland Valley road, we should not venture to repeat .ill that we have heard of their performances, it is enough to say that they are said to do more, in proportion to their weight, than any other engines now in use. The author believes that the Railroad Advocate's claim of Smith's design of the Pioneer has been confused with his design of the Utility (figs. 6, 7). Smith designed this compensating-lever engine to haul trains over the bridge at Harrisburg. It was built by Wilmarth in 1854. According to statements of Smith and the Board of Managers quoted on page 244, the Pioneer and the Jenny Lind were not new when purchased from their maker, Seth Wilmarth. Although of recent manu- facture, previous to June 1851, they were apparently doing service on a road in Norwich, Connecticut.
