Among the L&N's 4-4-0 locomotives with smaller drivers were 15 built in 1869 and 1870 by Baldwin. The first batch built in 1869 was numbered 67 to 76 and the second batch of 1870 became numbers 83 to 87. In 1873, two were rebuilt and two years later, No. 76 received three new driving axles with smaller drivers. In 1897, they were renumbered to 17 to 31.
