This ready-to-run N Scale PC&F Class R-70-13 Steel Mechanical Reefer No Roofwalk from Micro-Trains is based on steel reefers built in the 1960s for handling produce and other perishables. This detailed car features an injection-molded styrene body, separate fine-profile foot stirrups, a die cast underframe, free-rolling Delrin(R) trucks with contoured axles and truck-mounted Magne-Matic(R) magnetic knuckle couplers. The PC&F Class R-70-13 Reefer lacks a roofwalk because it′s based on cars built or modified after roofwalks were outlawed. Check out the entire line of Micro-Trains N Scale freight cars.
