There is no damage or defects, just very slight play wear. The powered unit runs great and the E-unit functions properly. The motor in the powered unit is weighted which along with the traction tires gives it great traction and pulling power. The non-powered B-unit shows almost no wear and rolls great. Metal hook couplers between the two units. Marx wedge coupler on rear of B-unit. O-gauge, 3-rail, O-27 scale. Overall length is 23 1/2".
