Thank you for viewing. Kato N Gauge Unitrack Structure ● 20-876 V16 Outer Double Track Set .R480/447 ● 20-874 V15 Double Track Station Track Set ● 23-123 Suburban Elevated Station Building Expansion Set ● 23-120 Suburban Island Platform Set ● 23-109 Suburban Island Platform End B ● 23-107 Suburban Island Platform A x 3 sets ● 23-108 Suburban Island Platform B x 3 sets ● 20-000 Straight Track 248mm x 5 sets (20 pieces) These are expansion sets for tracks and stations. You can enjoy this product by preparing a power pack and your favorite vehicles without using 23-123. If you need anything else, please prepare it separately. If you build a regular endless track, you will need additional double track straight track 248mm. I have about 4 sets (8 pieces) in stock. If you need them, please let me know before you purchase. Although they are new and unused, some of the package boxes have discoloration. There are no problems with the contents. If you have any questions, please feel free to comment.
