Inspired by the dual-rail tracks train, the motion characteristics of water droplets on the dual-rail hydrophilic tracks was studied, and its mechanical mechanism was revealed. First, the superhydrophobic surface of stainless steel was prepared by spraying method, and then different types of hydrophilic tracks were processed on the superhydrophobic surface by laser etching. The motion behavior of water droplets on different tracks was studied, the relationship between water droplets motion state and tracks parameters was discussed, and the mechanical properties of water droplets motion was analyzed. The results show that the movement resistance of water droplets on the parallel dual-rail tracks is about 1.6-2.4 times that of the single track, and is positively correlated with tracks width and negatively correlated with tracks spacing. The termination state of water droplets movement presents three types:stagnation in the middle of the tracks, stagnation at the end of the tracks and separation from the end of the tracks. The movement resistance of water droplets on non-parallel dual-rail tracks is related to the movement direction, and the movement resistance from wide end to narrow end is smaller than that from narrow end to wide end, which is about 90.7% of latter. It is concluded that the movement resistance of water droplets on the tracks is mainly affected by the contact area between water droplets and hydrophilic tracks. When the spacing of parallel dual-rail tracks increases, the stretching effect of water droplets in the vertical tracks direction will enhanced, then the water droplets will shrink along the parallel tracks direction and the spreading length will decrease, so the contact area between water droplets and hydrophilic tracks decreases, which lead to the movement resistance of water droplets reduced. However, the resistance difference of water droplets in different directions of non-parallel tracks is related to the surface tension of water droplets.
