To provide a water tank whose weight is reduced as much as possible without decreasing a conventional volume and whose durability while traveling at high speed is high in a water tank for a railway vehicle.SOLUTION: A water tank for a railway vehicle is composed of a rectangular cross sectional cylindrical barrel part 4 fixed under a floor board 2 of the railway vehicle and an end plate 5 closing at least one opening 8 of the cylindrical barrel part water-tightly. The end plate is composed of a rectangular plate shape body part and a bent plate part provided bent for an edge on each side of the body. An end surface of the opening of the cylindrical barrel part and an end surface of the bent plate part are bonded by butt-welding. A reinforcement member 7 fixed inside the cylindrical barrel part, and a wave removing plate 9 are fillet-welded on a front surface and a back surface of the bent plate part.SELECTED DRAWING: Figure 1
