The Baltimore and Ohio Railroad (B&O) provided early motive power (locomotives) and rolling stock to the Allegany County coal short line railroads. The B&O supplied at least eight Camel engines to the MMC, as evidenced in notes by locomotive builder Ross Winans. These included B&O engines nos. 161, 162, and 163, among others. In addition, Winans, among other builders, sold engines, tenders, and coal hoppers to the various mining companies. Passenger service was provided on the Eckhart Branch sometime before 1853, and the C&P continued to use a gravity passenger car on that line. The passenger car was then hauled back up the mountain at the end of a string of empty coal hoppers. Servicing, watering, and coaling facilities were located in Eckhart. The C&P maintained an engine house and servicing facilities here, and the foundations of these were still evident in 1999.
