Freda might confirm, but from memory, the main reason for the 'renovation' was to get rid of the undulations in the straight. The issue with the track at the junction, actually from about the 500, has been there ever since and is due to the shallow topsoil layer, especially in that part of the track, over the clay base that they decided to lay. We all saw it happening. A plough and discs indeed may not be flash enough but I think that with the mission to centralise and the movement to overuse crap tracks like Riccarton, means that they are not prepared to put them out of service for the required 12-24 months every 5-7 years in order to do the necessary restoration, which I agree with you Reefton could be done exactly as you suggest. Maybe not Riccarton because there's probably not enough topsoil to work with in places.
