Within Rogers' own shop, William Swinburne worked as the shop foreman until he moved on to form his own locomotive manufacturing company, Swinburne, Smith and Company in 1845. After Swinburne left Rogers, John Cooke also worked at the Rogers plant. Like Swinburne, Cooke later went on to form his own locomotive manufacturing firm, Danforth, Cooke & Company. Another engineer who worked at Rogers was Zerah Colburn, the well known locomotive engineer and, later editor and publisher. Colburn was, around 1854, "superintendent and/or consultant" at the works where he introduced a number of improvements in locomotive design. His assistant was William S. Hudson who succeeded Rogers after he died in 1856, and was responsible for further engineering enhancement. Hudson would remain with Rogers until his own death in 1881.
