NC&StL No. 170 Big Mary

Nashville, Chattanooga & St. Louis No. 170 Big Mary was a steam locomotive that worked on the Nashville Chattanooga & St. Louis Railway until December 1933.
== History ==
The locomotive was built by the Rogers Locomotive & Machine Works in 1870 and originally started life as Nashville & Chattanooga Railroad Company #64 and was given the name "Big Mary" since the locomotive was the biggest on the roster at the time. The locomotive was rostered as a pusher locomotive on the Cumberland Mountain. After the N&C merged with the Nashville & Northwestern Railroad in 1873 to become the Nashville Chattanooga & St. Louis Railway Company, the locomotive was then renumbered to 40, but still kept its name. After being rebuilt in 1903, the locomotive was renumbered to 260. In 1915, "Big Mary" was classified as a GO class ten-wheeler and was renumbered to 170. The locomotive then saw service on the Huntsville Division, retired in 1933 and scrapped.
