This is a characteristic con-dition of damaged cars which arcbraced in this way. As far as any pro-tection to the end sill is concerned,except for corner blows, the diagonalsmight as well not be there as to bearranged as shown in Fig. 2. There is another matter of centersill construction that may be mentionedin this connection, and that is the useof an arched upper cover plate. Thisform is used for the double purpose of )N.\I„s : ,. _\ It apparently fails to stiffen the centersills between the bolsters and, wherethe total sectional area of the centersill does not have a wide margin ofstrength, the arched cover plate seemsto add little to the strength of the sillswhen considered as a column.
