Roco 7520030 H0 Electric locomotive 420 268-5, SERSA, Ep. VI, AC sound: Versatility and digital innovation for your model railroad

The Roco electric locomotive 420 268-5 from the Rhomberg Sersa Rail Group brings the proven technology of the Re 4/4 II to the world of model railroads. This model combines the latest digital functions, realistic sound effects and a precise reproduction of the locomotive, which was taken over by Sersa AG after being taken out of service by the Swiss Federal Railways (SBB).

The prototype: Re 4/4 II in the service of Sersa AG

After the Re 4/4 II was taken out of service by SBB, two locomotives were taken over by Sersa AG, a leading Swiss railroad engineering company. Sersa AG specializes in track construction, track maintenance, the construction of overhead contact lines and measuring systems for railroad lines and railroad technology projects. The locomotives are now used in the private railway sector and are deployed for both heavy freight trains and shunting tasks. The Re 4/4 II has established itself as a reliable workhorse in daily rail operations.

Detailed design and modern technology

The model of the Roco 420 268-5 impresses with numerous detail upgrades. The locomotive is part of the 2nd construction series of the Re 4/4 II and has many separately attached plug-in parts, some of which are made using etching technology. Particularly noteworthy is the innovative pantograph, which ensures high stability with a special attachment. In digital operation, the locomotive is equipped with switchable headlights or marker lights, cab lighting and engine room lighting, which gives it a particularly realistic appearance. The Z21 cab system allows even more realistic control and offers additional digital functions.

Technical features and digital functions

The locomotive is equipped with an AC sound decoder that reproduces realistic driving noises, braking noises and signal horns. The lighting is provided by maintenance-free LEDs that change the light between red and white. The model also has interior lighting that allows the driver's cab and engine room to appear in a realistic light. With a length over buffers (LüP) of 177 mm and a minimum radius of 360 mm, the model is suitable for all standard H0 layouts. The NEM coupling system with close coupling kinematics guarantees safe operation and simple coupling with other vehicles.

Why this model is an enrichment for your collection

The Roco 7520030 H0 electric locomotive 420 268-5 is an excellent choice for model railroaders who want to authentically represent the private railway sector in Switzerland in Era VI. With its detailed replica, extensive digital functions and realistic AC sound, this locomotive offers an incomparable driving experience. It is suitable for both digital operating environments and classic H0 layouts and will cut an impressive figure in any scenario.

Care and maintenance

The LEDs and the sound decoder are maintenance-free, but the wheels and couplings should be cleaned regularly to ensure perfect operation. The fine details and precise printing require careful handling. Dust can be removed with a soft brush to preserve the brilliant appearance of the model.

Conclusion: Perfect technology for your model railroad

With the Roco 7520030 H0 electric locomotive 420 268-5, you can expand your model railway layout with a powerful and detailed locomotive that combines modern digital functions with historical precision. The extensive sound functions, realistic lighting and high-quality workmanship make this model an indispensable addition to your collection.
