Mors Smitt Railway technology Mors Smitt is entirely devoted to develop and manufacture electrical equipment, components and control solutions for railway and trackside applications. Mors Smitt has become leading in this demanding market. We supply the largest international rolling stock manufacturing enterprises as well as the main world rail operators. Mors Smitt has been manufacturing relays since 1902. We have a wide range of relays fit for all railway rolling stock applications. Our technology was developed in the 1960’s and has proven itself over time and is still the most reliable...

New solutions are co-designed with railway operators and contractors, creating safer railway networks
