The invention provides a lower-layer chassis and a double-layer railway vehicle with the lower-layer chassis. The lower-layer chassis comprises a bottom chassis and two side chassis bodies arranged on the two sides of the bottom chassis. The side chassis comprises an upper edge beam, a lower edge beam, a side plate and multiple upright posts; the multiple stand columns are perpendicularly connected to the upper edge beam and the lower edge beam respectively, and the side plates are welded to the upper edge beam, the lower edge beam and the multiple stand columns. The bottom chassis comprises a floor, a plurality of cross beams and two square cross beams, the cross beams are arranged on the floor in parallel at intervals, the two square cross beams are arranged at the two ends of the floor respectively, the lower face of each square cross beam is welded to the floor, and the side face of each square cross beam is used for being welded to the sealing plate of the inclined end chassis, and the upper plane is used for being connected with the stand columns of the inclined end chassis. The vehicle body with the lower-layer chassis is good in strength, rigidity and corrosion resistance.
