Thank you for viewing. This is a listing for Marklin HO curved track 5120 x 8 pieces and straight track x 2 pieces, with confirmed power conductivity. The curved track is the rare Marklin 5120, the smallest radius. The 5120, when connected in a set of 4, forms a half-circle with a diameter of 57.2 cm (catalog value), the smallest among Marklin's M track. Compared to the more common 5100 (requires 6 pieces for a half-circle, catalog value diameter 72.0 cm) and 5200 (requires 6 pieces for a half-circle, catalog value diameter 87.5 cm), the 5120 is significantly less common. When an oval course is made with 5120, it can fit on a slightly larger table in your home, making it a popular item for easily enjoying HO gauge. For this listing, I have checked the power conductivity with a digital multimeter and conducted running tests with various vehicles with different axle colors. All vehicles ran without any problems. When connecting the tracks, there may be some areas that are difficult to connect depending on the compatibility of the rails, so please try reconnecting them if this occurs. (Contents) Curve 5120 x 8 pieces Straight 5106 x 2 pieces (one of which is a feeder rail for power supply) Although power conductivity has been confirmed, these are old items, so there is some rust and deterioration. Therefore, the condition of the product has been set to "with scratches and dirt." As these are vintage items that have been in someone's possession, please understand that no returns or exchanges are accepted. Shipping costs will be covered by the seller, and items will be shipped anonymously. Marklin KATO TRIX HO Eisenbahn Märklin
