A short cutting (length: 43 metres) provides access to two tunnel tubes, both of which are 2,082 metres long. At the east end they emerge into a cutting with a depth of 18 metres. The line climbs for 500 metres until it reaches ground level, where the next line construction lot starts.
The Osterberg Tunnel construction lot includes the two portals, the surface drainage system, roads alongside the track, emergency access roads and a retaining wall adjacent to the protected FFH area of the dry slopes by Steigra (Trockenhänge bei Steigra).
