Indispensable components of any large model railroad are amplifiers (here called „Booster“): If the power consumption of all of your moving trains including their functions, car illumination, and function models is larger than the current the central station is able to put out, you have to split up your layout into several blocks, the power for which is supplied by their own booster. The ECoSBoost(er) is designed for precisely that task: It is matched perfectly for the use with our ESU ECoS or the Märklin® central station.
