Roco 7500075 H0 Zahnradbahn-electric locomotive, Sonnblick-Bahn, Ep. III - IV

Roco 7500075 H0 Cogwheel electric locomotive of the Sonnblick Railway: A masterpiece for challenging terrain

The Roco 7500075 H0 cogwheel electric locomotive of the Sonnblick Railway, inspired by the E 69 series, combines impressive technology and a historic design. With its ability to negotiate gradients of up to 35% on rack and pinion tracks, it is an indispensable model for model railroad layouts with mountainous terrain.

The prototype: Cog railroad of the Sonnblick-Bahn

Rack railroads offer a unique driving experience by mastering steep gradients and challenging routes. They are propelled by a cogwheel that engages with a central rack. This enables safe operation on routes where the friction between wheel and rail alone is not sufficient. Many Alpine cog railroads combine friction and rack and pinion tracks, which makes them particularly versatile.

The Sonnblick-Bahn is a fictitious representative of such railroads, which are mainly found in tourist regions of the Alps. It combines technical know-how with the beauty of Alpine landscapes.

Epoch III-IV: Technical progress and mountain romance

Era III-IV (1945-1970) marks the transition from steam locomotive to electric locomotive technology and the increasing use of private and tourist railroads. The rack-and-pinion electric locomotive depicted here shows the state of the art technology that was developed at this time for demanding mountain routes.

Color scheme and design

The locomotive is compact and functionally designed to provide excellent performance even on narrow and steep routes. The model's attention to detail is evident in the fine proportions, the 3 headlights and the ability to run on both rack and standard tracks.

Recommended purchase for model railroaders
