This is a set of the E5 Series Shinkansen Hayabusa and E6 Series Shinkansen Komachi, along with curved rails, mini bridge piers, and a block pier set. My child loves these and I bought many new ones, but I have duplicates, so I'm selling these while they're still new and in good condition. I believe I purchased everything at Yamada Denki. - Set Contents: E5 Series Shinkansen & E6 Series Shinkansen Combined Set Curved Rails (4 rails per pack) x 4 packs Mini Bridge Piers (16 pieces per pack) x 1 pack Block Piers (6 pieces per pack) x 1 pack Two packs of curved rails can make one circular track.
