See data from EJ&E 11 - 1938 Locomotive Diagrams supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange.
This somewhat ornately calligraphed diagram shows a typical Eight-wheeler of the late 1880s. Apparently it remained in service even in the late 1930s on runs that cannot have offered much speed.
