In this respect these original Balti-more 6c Ohio locomotives were prototypesof the heavy electric locomotives built since1907 for passenger service on other linesentering New York City. It will be easily realized that a number ofnew problems presented themselves in thispioneer installation and a number of newfeatures had to be incorporated, but the ELECTRIC LOCOMOTIVES IN THE BALTIMORE BELT LINE SERVICE. NEW PREIOnT ELECTRIC LOCOMOTIVE success of the installation can be seen fromthe fact that the original locomotives arerunning today and doing satisfactory servicein hauling passenger trains. The locomo-tives had a capacity of 28,000 pounds trac-tive effort, at a speed of sixteen to twentymiles per hour, corresponding to approxi-mately 1,200 horsepower. About ten years later, the extension ofthe service and its increased requirementsdemanded additional locomotives, and itwas decided to adopt a type of locomotiveparticularly suitable for freight service. The frt;ight locomotives of 1903 are shownin the illustration, and are today the hea\ iestelectric locomotives in operation. weighs 160 tons and is built intwo 80-ton halves, coupled together andcapable of being operated by one half unit is equipped with four motorsgeared to the axles.
