The Interessengemeinschaft 3-Seenbahn e.V. is a German heritage railway located in Schluchsee-Seebrugg in Black Forest. It was founded on 13 January 2008 to prevent the demolition of the former freight yard in Seebrugg. At certain dates all over the year the volunteers organize and operate vintage train rides on the Three Lakes Railway (Titisee – Seebrugg) and on the Höllentalbahn (Freiburg – Titisee – Donaueschingen)
