Laser-Cut Kit Steel Bridges H0 Both truss bridges for overhead tracks are made of a special laser cardboard. These high-quality kits are not lacking in detail. The rivets of the steel construction are formed by laser and the surfaces of the planks on the top of the bridge are exquisitely structured. Additionally, each kit contains two bridge heads made of high-quality NOCH structured hard foam (3.15 in. wide, 5.04 in. high). The kits are assembled with standard glue such as UHU. The bridges are convenient for all H0 track systems.
