The outside corners of the threshold plate 40 are cut away at and the flange 41 of the plate extends to the extreme edge of the plate 36, and the web 42 and the flange 43 both terminate at the edge of the adjacent flange 35 of the respective door posts 32 all as best shown in Figure 3. Each door post 32 is positioned directly over one of the crossbearers 17 and rests partly upon the horizontal flange of the respective side sill section and partly upon the support 25 and is welded to the horizontal flange of the side sill section and the support, and the side sheathing 14 is welded to the web 33 of each door post. A T-shaped member 46 is disposed at each door post 32 and extends substantially full height of the door opening 16 and has a first arm 47 welded to the adjacent flange 34 of the respective door post and a second arm 48 welded to the adjacent flange 35 of the ost.

p A Z-shaped side plate member 49 extends the full length of the car and is disposed at the top of the door opening 16 and one flange 50 projects under the roof 13. A Z-shaped member 51 is positioned at the top of the door opening 16 and extends across the door opening and the top edge of the member is in alignment with the tops of the door posts 32 and a llange 52 is disposed in abutting relation with the flange 53 of the side plate 49. A plate 54 extends across the door opening 16 and the ends of the plate are partially cut out and fitted in similar cut out in the side edges of the plates 36 and the top edge of the plate 54 is in alignment with the top edges of the plates 36. A plurality of rivets 55 extend through the roof sheet 13 and the flange 50 of the member 49 and the plate 54 at the door opening, and beyond the door opening to each end of the car these rivets extend through only the roof sheet and the flange 50 of the side plate 49. A top retainer 56 has one flange disposed in Iabutting relation with the outer face of the flange 53 of the angle 49 and a pluralityof rivets 57 extend through the flange of the top retainer and the flange 53 and the flange 52 of the angle 51. The side sheathing 14 is welded to the flange 53 of the side plate. A T-shaped member 46 extends across the door opening 16 and has Ian arm 47 welded to the web 58 of the member 51 and a second arm 48 welded to the flange 59 of the member 51. The plate 54 is also secured to the flange 59 of the member 51 by a weld 60. A track 61 is disposed below the door opening 16 and this track is welded to a plurality of spaced supporting plates 62 which are in turn welded to the vertical flange of the side sill reinforcement 22. The track 61 and the top retainer 56 serve to support and hold a door in vertical position on the side wall so that it can be moved in a direction parallel to the side wall to a position covering the door opening 16 or to a position removed from the door opening.

The present door opening construction is particularly adapted for a door of the type that is first slid longitudinally of the car in a position parallel with the side wall to the door opening and upon the door covering the opening is moved transversely of the car to fully closed position where the inner face of the door bears against the web 42 of the threshold 40.

It is to be noted that the side sill is completely cut away across the door opening and that a support is interposed between the side sill sections which has a flange interposed between the ends of `the cross lmembers and the side sill reinforcement. It is to be noted also that the floor is spaced inwardly from the door opening so that a door that is movable transversely of the car into and out of the door opening can be moved to a position where the inner face of the door is flush with the side wall inside lining which is the fully closed position and the inner face of the door bears against the web of the threshold member. The cross members, the support, the floor, the side sill reinforcement, the threshold, and the wear plate together form a construction at the bottom edge of the door opening that is of great strength. The hat-shaped door post with the plate and the T-shaped member secured thereto also provides a construction of exceptional strength at the front and rear edges of the door opening. The two Z-shaped members and the plate and the T-shaped member together provide a construction that will withstand great stresses at the top edge of the door opening.

From the foregoing it will be seen that there has been provided various constructions at the bottom, top, front, .and rear edges of the door opening which together form a door opening construction that will withstand great impacts and forces and will maintain the rectangular shape of the door opening.
