Ida Valley Ballast Pit is located near the 95 mile peg of the Otago Central Railway between Ida Valley and Oturehua. It was open only during the construction era – between 1903 and 1904 – and was a tablet station. Because that latter fact I now have to locate exactly where it was and mark it on the map as a closed station.
Here is the amended map.
The locations for the coaling and watering facilities are correct, however the exact location of the tablet station is uncertain.
