Service on the Eckhart Branch was hard, as evidenced by a series of correspondence with the Winans works in Baltimore in 1856. On June 16, 1856, CC&I ordered a replacement right-hand crosshead for the "Braddock." The "Braddock" had gone into service on July 1, 1854. On September 24, they needed the same part for the "Eckhart." The "Eckhart" had been placed into service on August 1, 1849. A frantic telegram on December 9, 1856, emphasizes the need for urgency for shipment of the replacement left-hand crosshead for the "Eckhart". The engines "Black Monster" and "Cumberland" were at work at that time. The parts were delivered to the B&O Railroad at Cumberland. It is not known whether the repair work was done at Cumberland, or at Eckhart. The engine "Eckhart" was later rebuilt at the C&P shops in Mount Savage in 1868.
