The company “RAIL TECH” Igor Marszałek, already established on the mobile railcar service market, becomes a part of KZN Switcher to provide foundations for the development of servicing potential.


Rail Tech has cared for the technical condition of freight railcars in Poland and neighbouring countries for more than a decade. With mobile service teams, Rail Tech has been able to quicky and efficiently arrive at the place indicated by the customer, diagnose even the most complicated defect and repair any type of freight railcar. Since its inception, the company has been run by Igor Marszałek, a distinctive and recognizable manager whose competence and professionalism are now the real and exacting reference for the technical service provided by mobile teams in Poland.


The cooperation with the KZN Bieżanów Group started in 2019 and comprised periodic repairs and maintenance of SWITCHER cars. The decision to establish KZN SWITCHER accounted for the need to integrate Rail Tech and include it in the service and production structures of the new company.
