Cumberland and Knox Railroad

The previous operator of the Rockland Branch, Midcoast Railservice, ceased operations in 2024 after the closure of the line's primary customer, Dragon Cement.^[2] The Maine Department of Transportation selected Maine Switching Services as the new operator in January 2025.^{[3][4][5][6][7]}

Maine Switching Service announced the "Cumberland and Knox Railroad" name in April 2025, and service began on May 31, 2025.^[8][9][10] In October 2025, the CKRR purchased two passenger cars from the Adirondack Railroad, with plans to buy a third in the winter. The Midcoast Rail Heritage Trust, the operator of the Belfast & Moosehead Lake Railroad passenger services, plans to use these passenger cars alongside CKRR locomotives as a tourist train called the Pen Bay Scenic Railroad. This service is scheduled to open in 2026.^[11]
