Little River Railroad No. 110
The Little River Railroad in Tennessee had steep grades which also had tight curves at the same time. In 1911, Baldwin delivered the number 110 to them for their passenger trains, which was built with an extra short wheelbase and is considered the smallest standard-gauge Pacific in the world. It has a large grate for burning low-quality coal, but no brick arch and no superheater.
It pulled the “Elkmont Special,” which started in Knoxville until 1938, when the Little River became a pure logging railroad again. The 110 was now purchased by the Smoky Mountain Railroad and pulled freight trains there until 1954. Since 1976 it has been running on the new Little River Railroad, which is based in Michigan. It is still used there today as the flagship of this heritage railroad.
