The problem of train localisation on some part of the railroad is still an open question. Indeed, when electrical systems are used, the train is localised due to variation of an electrical signal: It is the shunt phenomena. But if the wheel-rail contact is insulating enough, the signal intensity is not affected and the train is invisible for the rail operators, and can lead to dramatic accident. Among the several parameters which can be involved, the impact of the brake shoe composition is investigated.
