The GE 70-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between about 1942 and 1955. It is classified as a B-B type locomotive. The first series of "70 tonners" were a group of seven center-cab locomotives built for the New York Central Railroad in November 1942. These units differ from the later end-cab versions. Locomotives exported to Brazil were known as GE 64T (70 short tons or 63 long tons or 64 metric tons) and nicknamed "scooters".
