Locomotive No. 37 was used in 1871 when the South Side, Norfolk and Petersburg, and Virginia and Tennessee Railroads were consolidated, forming the Atlantic, Mississippi and Ohio Railroad. The AM&O was the forerunner of N&W.
Engines No. 14 and No. 37 collided at Rural Retreat. Note the collapsed front half of the first baggage coach. While engines could often withstand collisions, the wood-constructed baggage and passenger coaches were extremely vulnerable.
