The renewal of the formation and the provision of new track drainage between Harrow and South Kenton became necessary when ballast became choked, resulting in the prevention of effective drainage and the formation of slurry which flowed into the track drains. The first stage in the renewal is the removal of track in one line of the natural formation to withstand the loading of traffic. The next stage is the graduation of the formation to a crossfall to the new drainage system. A sand blanket of sufficient thickness to blind the clay and prevent it pumping and fouling the ballast is then laid to the required crossfall, the drainage system is placed, and the track ballast unloaded. The track is then reinstated and fettled up.
