This was a group of 18 2-4-0WT passenger steam locomotives, built by Robert Stephenson & Company and an extra locomotive built from spare parts supplied with the other 18. These locomotives not only provided the bulk workforce of the early private railway operators in Victoria, but upon their withdrawal they once again proved themselves as useful as contractors locos building some of the railway lines for the then expanding Victorian Railway network.
