According to numerous sites I looked at the Sunbury and Lewiston Railroad came to exist in 1870 in a reincorporation.

The railroad played a vital role in the development and expansion of McClure. Work of grading began in the summer of 1867. In 1870, the name was changed to Sunbury and Lewistown Railroad.

The origins of the Selinsgrove (pronounced SEAL-ins-grove) Industrial, like many lines throughout the nation, trace back to the post-Civil War railroading boom. Local business leaders promoted and planned a line east-ward from Lewistown (a junction with the original Pennsylvania Railroad Main Line, later the Middle Division) through the Middle Creek Valley to the Susquehanna River at Selinsgrove, incorporating as the Middle Creek Railroad in March 1865. Only minor con-struction ensued over the next five years. The company was reincorporated as the Sunbury & Lewistown Railroad in 1870, opened from Lewistown through McClure, Middleburg, and Selinsgrove to a junction with the former Northern Central at Selinsgrove Junction, 43.5 miles, on December 1, 1871.

The Mifflin & Centre County Railroad (M&CC RR) was projected to build northward through this iron belt, from Lewistown to Milesburg. By 1865 the line only extended 12 miles to Milroy with there being no favorable route northward over the Seven Mountains to Milesburg. In May of 1865, the PRR leased the M&CC RR and for years handled enormous traffic to and from Burnham Steel Company, successor of the Freedom Forge. Entrepreneurs also projected a line eastward from Lewistown to the Susquehanna River at Selinsgrove, PA incorporating the Middle Creek Railroad in 1865. Despite having constructed some roadbed, the line was waning by 1870 when it was reincorporated as the Sunbury & Lewistown Railroad.
