Elevated railway structure in N scale, compatible with Kato Unitrack. This kit permits to build a double tracked straight section of 372 mm length, or two sections of 186 mm. The kit contains 4 plate girder bridge sections, each 186 mm long, all parts for 5 double column bents, 4 sections of dummy 3rd rail and 10 screws M1.6 . You have to purchase otherwise: Kato N profile 21-000 and Kato 24-815 UniJoiners. The kit is easy to build, you just need to be familiar with cutting flex track to a precise length. Please notice: this kit is produced mostly "on demand", even if there are always some parts in stock. Production could require some extra days before shipping.
