The connection from Innsbrucker Platz station to the depot was severed when a deep level motorway underpass was constructed in the early 1970s; however, the continuation of the tunnel at Eisackstraße is still in existence for a distance of 270 metres and now ends at the former junction to the workshop of the Schöneberg line.
Hubungan dari stasiun Innsbrucker Platz menuju depo mengalami kerusakan saat sebuah jalan raya bawah tanah dibangun pada awal tahun 1970an; namun lanjutan dari terowongan di Eisackstraße masih tetap ada sepanjang 270 meter dan sekarang berakhir di bekas persimpangan menuju bengkel di jalur Schöneberg.
