This signal box symbolises in an ideal way the typical smallmechanical signal box. The tensioners for the wires with their weights are located at ground level adn can be accessed via a seperate entrance. The actual controls are at the upper floor. The linkage of the signal box to the railway is an important aspect of modelling such a signal box. (Wires leading to the turnouts and signals). the necessary shaft for the direction changing rolls is included below the jutty. A fascinating model that finds a place even on the smallest layout.
