This is a set of four model train cars: two powered cars from the Railway Collection Vol. 6, Odakyu Electric Railway Deha 1607 and Kuha 1657, and two cars from the Railway Collection Vol. 3, Odakyu 2200 series. (Regarding 1607 and 1657) These cars have been fitted with dedicated power units and can run. The pantographs have been replaced with dedicated ones. The couplers have been replaced from the standard Arnold couplers. (Regarding the 2200 series) These cars do not have power units installed. The pantographs are missing. Only the wheelsets on the coupler-equipped trucks have been upgraded to metal wheels. (Common Items) There is no dedicated blister pack, so the cars will be shipped in a case that previously held other vehicles. Please consider the case as packaging material. *There is no cushioning material to fill the gaps, so you may want to prepare your own if you intend to use the case for storage.* These cars were used for running on a layout, not just for collection or display. Please refrain from purchasing if you do not understand that these are used items or if you are looking for a perfect, mint-condition product.
