Roco 7110050 H0 steam locomotive Ok1, PKP, Ep. IV, DC-Sound

Roco 7110050 H0 Steam locomotive Ok1 - DC sound model of the Polish State Railways

With the Roco 7110050 Ok1-37 steam locomotive, Roco is bringing a high-quality edition model of the legendary Prussian P8 in its Polish version as the Ok1 series of the PKP (Polskie Koleje Państwowe) to the H0 tracks. This DC sound version impresses with modern digital technology, striking ornamental design and the finest model realization - a must for international steam locomotive fans of Era IV.

Digital sound experience without steam

For the first time, this model appears exclusively with sound, but without dynamic steam output - ideal for model railroaders who value clean technology and acoustic reality. The integrated PluX22 decoder provides realistic locomotive sounds for DC operation. In addition, the digitally switchable cab and engine lighting provides atmospheric scenarios in the dark.

Fine details & decorative lines for collectors

The locomotive is presented in a particularly eye-catching design with decorative lines on the wind deflector plates and the carbody - a real eye-catcher. Many separately attached plug-in parts and filigree spoked wheels underline the high level of detail of this model. The in-house coupler with close coupler kinematics ensures close car transitions and prototypical train formation.

Historical classification - From the P8 to the Ok1

The Prussian P8 was one of the most successful steam locomotives in Europe. After the First World War, Poland received a total of 192 units from German stocks, which from then on were operated by the PKP under the designation Ok1. Over the years, the PKP used a total of 429 locomotives of this class - a backbone of Polish local transport until the 1970s.
