Medha group (Enika) has played a crucial role in the modernisation of Siemens Combino trams in Poznan, Poland . Enika has supplied and integrated a comprehensive range of advanced components, including drive systems, static converters, control systems, and driver’s cabin accessories.
The modernisation project was part of a broader initiative by MPK Poznań to refurbish its fleet of 14 Siemens Combino trams. The first refurbished tram re-entered service in February 2023, marking a significant milestone in the city’s public transportation modernisation efforts.
Enika’s contributions have not only extended the service life of the Siemens Combino trams but also enhanced their performance and reliability. Passengers in Poznań now benefit from improved comfort and safety, while the city’s transit authority enjoys reduced maintenance costs and increased operational efficiency.
