早在加拿大Bombardler公司将其属下的蒙特利尔机车和柴油机工厂卖给美国在加拿大的GE公司时,GE公司就认真考虑了将该工厂转为改造机车生产基地的一部分的设想。最先考虑改造的一批机车是停放在美国GE公司所属的伊利工厂车间外面的剩余机车,GE公司将其改造的四轴和六轴机车命名为Super7。 As early as when Canada’s Bombardler sold its Montreal-based locomotive and diesel engine plant to a U.S. GE-based company in Canada, GE seriously considered the idea of ​​transforming the plant into a part of a converted locomotive manufacturing site. The first locomotives to be retrofitted were the remaining locomotives parked outside the Erie factory floor owned by GE in the United States, and GE named the modified four- and six-axle locomotive the Super7.
