The horizontal flange is secured to the underface of the roof sheet by a weld 20 in the angle between its end and the body of the sheet. The
edges of the ridge panels of adjacent sheets are preferably not flangedr but are spaced somewhat apart and the top edge of the free side of the carline member lies below the margins of adjacent sheets and spans the gap between their edges, and the sheets and carline members are all welded together by the single weld I1 which illls said gap.
In the construction illustrated in Fig. 1, the carline members extend from side plate to side plate and have their ends resting on and welded to the inturned legs of the side plate, and the running board 2i is made by merely painting and sanding the longitudinal ridge panel 8. In the construction illustrated in Fig. 8'however, the carline members |6a terminate considerably short of the side plates and are welded directly to the roof sheets; and the running board comprises a metal sheet Ila welded to in direct surface contact with the longitudinal ridge panel of the roof with its side margins extending beyond the inner ends of the channel panels Il so as to furnish grips for the trainmen.
The present roof has several advantages. Its flat longitudinal ridge panel is well adapted to support a running board without substantially increasing the thickness of the roof and it is adapted to be used as a running board by applying paint thereto and then applying grit or the like to the wet paint. In either case, it enables the ridge portion of the roof to be located close to the established tunnel clearance outline and it also enables the portions of the roof between said longitudinal ridge panel and the eaves to be located close to said clearance line. At the same time, the termination` of the depressed panels, at points outwardly from Athe longitudinal ridge panel, is made feasible by the use of the carline 'members with substantial decrease in the overall thickness or depth of the roof, particularly along the region of the ridge and thereby increases the headroom and loading capacity of the car. For this purpose, it is not necessary that the carline member shall extend to and rest upon the side plates, as the formation of the roof sheets into alternating ribs and channels enables them to take care of whatever load the carline members may pass to them. It is also noted that the invention allows considerable variation in the design of the carline members to adapt them to their location and to the stresses to which they m11 be subject and which they will pass along either to the side plates or'tol the roof sheets.
It is noted that the work of welding the carline member to the body portion of the sheet may be done at the factory and the sheet with the carline member welded thereto may be shipped as a preassembled unit. Such unit construction is not only economical, but facilitates the work of assembling the roof units into the complete roof.
