Energy management in railway applications involves an on-board energy measurement system (EMS) and ground-based data collecting system (DCS). These systems allow railway operating companies to manage energy cost for each train based on real, precise and controlled measurement under the regulation (EU) 2018/868 in Europe. By offering the on-board energy metering solution – TEMA4G – LEM supports the evolution of railway networks and meets the demand for management and optimisation of energy costs in railway transports.
TEMA4G combines LEM’s EM4TII+ on-board energy meter – already in service and proven in many trains – with an industrial modem offering 4G and GPS connectivity. Through its web interface the system allows users to access detailed load profiles, as well as numerous system parameters Meeting every vibration, shock, fire protection, and electromagnetic compatibility railway standard, TEMA4G is a perfect fit for new projects such as large retrofit programmes and supports railway operating companies of all sizes in a transition towards better energy monitoring, management and optimisation.
