It is not known if this is a complete list of Eckhart Branch locomotives. All of the listed engines except the first are of the "Camel" type. Hicks (ref. 23) recounts that the transfer records in the Maryland State Archives (from MMC to CC&I) mention five engines. Two of these are Winans, but lighter in weight than the listed engines, and three are much lighter. Rankin (ref. 46) mentions that the company motive power included three first class engines, two second class, and forty-one horses and mules. Rolling stock included sixty-eight iron hopper, gondola, scow, and passenger cars in 1853.
