Roco 7520110 H0 Electric locomotive Re 420 505-0, BLS, Era V, AC sound: Digital masterpiece with Swiss precision

The Roco electric loc omotive Re 420 505-0 of the BLS Lötschbergbahn is an outstanding model that combines the historical significance of this locomotive with the latest digital and sound technology. Originally in service with SBB as Re 4/4 II, it was sold to BLS in the 2000s and became an integral part of freight and passenger services. With extensive digital functions, including individually switchable lighting elements and AC sound, this locomotive is a highlight for any H0 model railway layout.

The prototype: From SBB classic to BLS all-purpose locomotive

In 2004, several Re 4/4 II locomotives were sold by the Swiss Federal Railways (SBB) to BLS, including the later Re 420 505, formerly Re 4/4 11137. The locomotives were urgently needed and initially ran in the SBB colors, but without emblems and chrome lettering. Instead, simple silver stickers were used. Gradually, the locomotives were given the BLS corporate colors and the Omega logo, which symbolized the takeover of the Regional Mittellandbahn (RM). The Re 420 505 was operated in green livery until 2009, when it was given its new look.

Authentic design and high-quality technology

The locomotive impresses with its prototypical design and the precise reproduction of the details. It is equipped with a delicate single-arm pantograph and modern LED technology. In digital operation, it has individually switchable headlights and marker lights, cab lighting and engine room lighting that make the model look particularly realistic. With a length over buffers (LüP) of 171 mm, it is ideal for H0 layouts.

Technical features and digital highlights

The model is equipped with a digital decoder and a high-quality AC sound module that produces realistic operating noises. The lighting is provided by maintenance-free LEDs with red-white light change. Thanks to the NEM coupling system with close coupling kinematics, the locomotive can be used flexibly and is suitable for track systems with a minimum radius of 360 mm. The Z21 driver's cab enables an interactive driving experience and underlines the high technical standard of this model.

Why this model is an enrichment for your collection

The Roco 7520110 H0 electric locomotive Re 420 505-0 combines historical authenticity with the latest digital technology. Its detailed design, high-quality digital functions and versatility make it an ideal choice for model railroaders who value prototypical replicas.
