Thank you for viewing. This is one set of the two I own. For the car spacing reduction test, I have partially replaced the couplers of two cars with 0396. These are the two cars visible in the case in the fourth photo. The couplers on both ends of the WaMu 1925 and one end of the Tora 73825 have been replaced. The others have the original couplers. The distance between the 0396 couplers has been shortened by about 2mm. The accessories and instruction manual are unopened.
