The invention relates to piling for rail tracks, and in particular to a method and system for piling railway tracks to improve the underlying foundation structure. Embodiments disclosed include a method of modifying an existing rail track structure comprising a pair of rails (309, figure 3) laid over a series of sleepers101 on top of a ballast layer 102. The method comprises forming a pile structure 201 extending vertically beneath and between adjacent ones of the series of sleepers, wherein a top 202 of the pile structure is separated from the series of sleepers by the ballast layer. The method may comprise inserting a tube between adjacent sleepers and through the ballast layer using an auger, removing the auger and inserting or forming the pile structure within the tube, and back filling the tube with ballast material. The pile may comprise a cemented column. The pile structure may comprise a cemented granular fill material and a reinforcement structure. The pile structure may comprise a metal outer casing.
