The New Park and Fawn Grove Railroad was incorporated on May 11, 1905 to build a line between Stewartstown (at a connection with the Stewartstown Railroad) and Fawn Grove, at a distance of 9.2 miles. The first phase to New Park was completed in February, 1906, with the remainder of the line completed in June of that year.
In 1923, the NP&FG was purchased by the Stewartstown Railroad, who continued operations on the line and ultimately abandoned it in 1935.
