D5.1 Hybrid coupler for legacy locomotives

Work Package 5 involves verifying the feasibility of installing DAC hybrid automatic couplers on the most common types of locomotives used by freight rail carriers in Poland, specifically the ET22 six-axle electric locomotive and the SM42 diesel shunting locomotive. It is important to note that both models exist in various configurations, ranging from classic versions to deep modernizations that significantly alter their technical parameters and physical appearance. The primary objective is to confirm the possibility of installing a hybrid coupler on both types of locomotives and, upon positive verification, to proceed with the installation and testing of a hybrid digital automatic coupler. 

Task 5.1 concerns work related to the preparation for the installation of a hybrid coupler on the SM42 locomotive. Its aim is to develop a standalone FDFT (Full Digital Freight Transport) system kit for the modernization of older locomotives. The specifications of the FDFT system set will be based on the specifications or results of the FP5-TRANS4M-R project and will include a Locomotive Control Unit (LCU), a hybrid-digital automated coupling system, an electric converter, and a Human-Machine Interface.
