Elevated railway structure in N scale, compatible with Kato Unitrack. This kit permits to build a double tracked straight section of 744 mm length, or FOUR SECTIONS OF 186 mm. The kit contains 8 plate girder bridge sections, each 186 mm long, all parts for 9 double column bents, 8 sections of dummy 3rd rail and 18 screws M1.6 . You have to purchase otherwise: Kato N profile 21-000 or Atlas Code 80N flex track, 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 always some parts in stock. Production could require some extra days before shipping.
