Introduced in 1955 to haul passenger trains on the New Haven Railroad, the EP-5s were nicknamed "Jets" after the roaring sound they made. In addition to their two main pantographs, the locomotives were equipped with third rail shoes and a third smaller pantograph for use on New York Central's tracks approaching Grand Central station.
When Penn Central took over the New Haven in 1969, the six EP-5s still in service were transferred to Grand Central - New Haven commuter trains and reclassified as E-40s. All were withdrawn from passenger service after 4971 caught fire in Park Avenue tunnel in 1973. 4973 and 4977 were rebuilt for light freight use and remained in service for a further three years until withdrawn by Conrail.
This version of the model depicts the locomotives in as-built condition, with fairings around the underframe equipment.
Included in the model are the main body and a sprue with the truck sideframes and all the handrails and other parts which need to be added separately, as illustrated in the diagrams above.
I recommend using acrylic paints for this model as they work well on the Frosted Ultra Detail plastic. Enamel paints have been reported to take an excessive amount of time to dry on Frosted Ultra Detail so should not be used.
