Please note that this is a used item. Includes 4 lead cars and 3 intermediate cars with pantographs, and 3 intermediate cars without pantographs, for a total of 10 cars. The powered car is one car, and the lights work well (see photos). Couplers are Tomix body TN couplers for connecting intermediate and lead cars (knuckle couplers, see photos). Dummy couplers are on the driver's cab side of the lead and last cars. All other couplers have been replaced with Kato close-coupling couplers. I don't have any particular preferences, so the actual formation may differ. There are no included accessories. The case is a genuine Micro Ace case, but it is for 10 cars, not a 6-car set. The paper sleeve has scratches and peeling.
