Roco 7120037 - H0 Class Pt 2/3 steam locomotive, K.Bay.Sts.B., Era I (AC sound)

With the Roco 7120037 you get a filigree and historically significant model of a light passenger tender locomotive in your home, which was in use in the early days of the Royal Bavarian State Railways. This locomotive impresses with fine details such as movable Heusinger controls, elegant decorative lines and a realistic design that makes it ideal for integration into sophisticated Era I layouts.

Product details & technical specifications

Design & finish

The locomotive has an elaborate paintwork with fine decorative lines and historically correct colors, matching the K.Bay.Sts.B. The slim boiler, the strikingly large distance from running axle to coupling wheels and the generously dimensioned driver's cab characterize the prototype - these elements are reproduced in great detail. Particularly noteworthy: The movable Heusinger control system brings the model to life and underlines the quality of the mechanics and appearance.

Special technical features & functions

Thanks to the integrated AC sound, the model offers not only visual but also acoustic liveliness. The movable controls increase the realism. As an AC model, it is particularly suitable for systems that rely on AC technology. (Note: The manufacturer's data explicitly mentions AC sound as a feature.) Whether a digital conversion is possible or variants with DC exist depends on designs and retrofit options - the model is currently listed as an AC sound variant.

Historical background

The Pt 2/3 was a light tank locomotive used in passenger service on the Royal Bavarian State Railroad. The first units went into service in 1909 and the last in 1916, designed by Krauss in Munich. The design is 1 B h2, maximum speed 65 km/h. Characteristics: slim boiler, large wheelbase differences (e.g. 4,000 mm distance between running and coupling axles) and rear door for access from the train compartment - an unusual feature.

Compatibility & expansion options

• Suitable for AC track systems in H0
• Layouts in the style of Era I: ideal in local or branch line settings
• Particularly suitable as a supplement to the passenger car serial number 6200197 (K.Bay.Sts.B.)
• Optional additions could be wagons with Bavarian local railroad prototypes
• Digitization option (if mechanically possible) could be realized by retrofit decoder or conversion - depending on the housing and space available
