This project is undertaken to mitigate the risk of embankment collapse in a section of the rail network near Taihape. The preferred slope risk mitigation design includes the construction of a landslide protection barrier.
The site is located on the NIMT line near Taihape. The site is part of the electrified rail corridor between Te Rapa and Palmerston North. The track consists of a single line over most of its length and traverses several cuttings in the region. The site is located between chainage 255.88km and 256.19km on the NIMT line.

The 255.88km site is a cutting on the left side of the track between the Taihape and Mataroa Stations. The cutting varies up to 15m but is typically 5m to 10m high. The site is surrounded by grazing farmland both upslope of the cutting and downslope from the rail corridor. The site slopes very gently up chainage. The slope is heavily vegetated with a mixture of shallow rooted and deeper root systems in some areas, with up to 10% of the slope being visible. The cutting has several historical slips and dropouts, which have since naturally revegetated. A 0.5m high 15m long debris fence is installed at the toe of the slope, likely to address historical instability at this location. The fence is made from rail irons with timber lagging that has degraded. Minor recent shallow failures and erosion were also observed in localised areas along the length of the cut.

The approved design as include in the tender documents incorporates the use of a landslide protection barrier.
