Abstract
In a third rail system for electric railroads, double T shaped third rails are used, the web of which has an internal longitudinal slot to receive the guide projections of support insulators and for the space saving mounting of electrical and mechanical connecting parts of fixed and/or expansion joints. With this slot design, good heat transfer and at the same time, a large mechanical moment of inertia are obtained.
