Canada Atlantic 4-4-0 #606

While both rosters agree on this origin, it is unlikely. According to Edson there was only one 16x22-61 locomotive disposed of by the B&O by 1882, the #271-General Sickles, which was built by Mason in 1863 (126). Not many locomotives with 16" bore were being built as late as 1875, and none by the B&O. So, either the specs are incorrect or the engine was earlier than 1875. Of the locomotives retired by the B&O in 1882, #271 is the most appropriate; however, other candidatess are the 2nd 34, 2nd 50 and 2nd 74 which were 14x20-60, built by Mt Clare in 1867.

The Marietta and Cinncinatti, which was controlled by the B&O after 1900, disposed of a number of 4-4-0's between 1874 and 1882. Of particular interest are M&C 38 (16x22-60, Rogers 1189 1864), M&C 39 (16x22-60-65500, Rogers 1190 1864) and M&C 40 (16x22-60-70150 Rogers 1196 1864). These Marietta and Cincinatti locomotives are particularly interesting because 606 bears a resemblance to other Rogers products.
