Data from "An Old Indian Engine", Locomotive Magazine, Volume XXIII [23] (15 October 1917), p. 212.
Three different builders, two from Glasgow and one from Yorkshire, supplied the standard goods locomotive for this railway beginning in the late 1860s. The small six-coupled design featured a tall chimney (stack), brass dome over the firebox, large cab, raked cylinders outside of the smokebox.
LM's report included a table of all the batches, reproduced below in road number order.
Road numbers Builder Works Numbers Year
7-10 Sharp, Stewart & Co 1937-1940 1869
11-31 do. 2003-2023 1870
32-45 do. 2105-2112, 2132-2137 1871
46-60 Avonside Engine Co. 813-827 1870
61-70 Sharp, Stewart 2633-2642 1876
71-76 Avonside 1159-1160, 1163, 1165, 1167-1168 1877
77-80 Dubs & Co 1073-1076 1877
81-90 do. 984-993 1876
After years on front-line service, heavier trains overmatched the Bs and they were relegated to shunting (switching) duties.
