The route would continue under the eastern apron of Munich Airport in a tunnel until it resurfaces near Schwaigerloh.

This allows for direct operation of long distance and S-Bahn trains from Landshut via Moosburg and Freising to Munich Airport.

An upgrade of the existing railway line to four tracks is initially not intended as an additional S-Bahn station in Mintraching is still being considered.

A project management office was established at the end of January 2007 for the preparation of tenders for the design of the line.
