         12 . A large component for a rail vehicle, comprising:
 a grid-like structure of bows and ribs; and   a paneling formed from said grid-like structure;   wherein the ribs are formed as planar sheet metal parts which are butt-welded to the paneling, and the bows are formed as planar sheet metal parts which are butt-welded to the paneling; and   wherein a C-rail is arranged on at least one of bow of the grid-like structure of bows.   
     
     
         13 . The large component for a rail vehicle as claimed in  claim 12 , further comprising:
 a C-rail arranged on the at least one bow;   wherein the C-rail is formed as a roll-profiled part which is butt-welded to the bow.   
     
     
         14 . The large component for a rail vehicle as claimed in  claim 12 , wherein the ribs have an outer contour which allows the C-rail to be mounted on the ribs in an assembly position. 
     
     
         15 . The large component for a rail vehicle as claimed in  claim 13 , wherein the ribs have an outer contour which allows the C-rail to be mounted on the ribs in an assembly position. 
     
     
         16 . The large component for a rail vehicle as claimed in  claim 14 , wherein the C-rail is welded to the ribs at at least one point. 
     
     
         17 . The large component for a rail vehicle as claimed in  claim 12 , wherein the large component is formed as a side wall. 
     
     
         18 . The large component for a rail vehicle as claimed in  claim 12 , wherein the large component is formed as an end wall. 
     
     
         19 . The large component for a rail vehicle as claimed in  claim 12 , wherein the large component is formed as a roof. 
     
     
         20 . The large component for a rail vehicle as claimed in  claim 12 , wherein the paneling is constructed from a plurality of metal sheets having different material compositions or thicknesses. 
     
     
         21 . The large component for a rail vehicle as claimed in  claim 12 , wherein the bows, ribs, paneling and the C-rail are welded via a laser welding method. 
     
     
         22 . The large component for a rail vehicle as claimed in  claim 12 , wherein the bows, ribs, paneling and the C-rail are manufactured from corrosion-resistant steel or non-corrosion-resistant steel. 
     
     
         23 . The large component for a rail vehicle as claimed in  claim 12 , wherein the large component is fitted with a window frame and a C-rail is arranged below the window frame; and wherein water inlet holes and water outlet holes are introduced into the C-rail.
