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.

What I claim is:

1. A car roof comprising side plates, roof sheets extending from side plate to side plate and having their ridge portions substantially flat for a width substantially equal to the horizontal top portion of the established tunnel clearance outline, said sheets having, at their side margins,

upstanding flanges that extend from the sides of the flat ridge portion to near the eaves, carline members located mostly below the sheets but having an upstanding portion between adjacent sheet flanges and with their tops substantially following said clearance outline and iiush with the tops of said flanges, and welds along said outline uniting adjacent sheets together and to the intervening carline members.

2. A car roof comprising side plates, roof sheets extending from side plate to side plate and having their ridge portions substantially flat and the portion between said ridge portion and each eaves broken conformably to the established tunnel clearance outline, said sheets having, at their side margins, upstanding ilanges that extend from the sides of the flat ridge portion to near the eaves, carline members below gaps between "adjacent sheets along said ridge portions and having an upstanding portion between adjacent sheet flanges with its top substantially flush with the tops of `said flanges, welds filling said gaps and opposite said edges and uniting adjacent sheets together and to the intervening carline members.

3. A car'roof comprising side plates, roof sheets extending from side plate to side plate, carline members located mainly below the roof sheets with portions extending upwardly between the edges of adjacent sheets, and welds close to the established tunnel clearance outline uniting adjacent sheets together and to the adjacent carline member, the ridge portion of the sheets for a width substantially' equal to the horizontal top portion of the established tunnel clearance outline being substantially iiat and close to said outline and the portion between said ridge portion and each eaves having breaks to conform such portion approximately to the established tunnel clearance outline and having a depressed panel extending along the middle thereof cross- Awise of the car.

4. A car roof comprising side plates, roof sheets extending from side plate to side plate, carline members located mainly below the roof sheets with portions extending upwardly between the edges of adjacent sheets, and welds close to the established tunnel clearance outline uniting adjacent sheets together and to the adjacent carline member, the ridge portion of the sheets for a width substantially equal to the horizontal top portion of the established tunnel clearance outline being substantially flat and close to said outline and the portion between said ridge portion and each eaves having breaks to conform such portion approximately to the established tunnel clearance outline and having a depressed panel extending crosswise of the car along the middle of said portion, said carline members being longer than the width of said flat ridge portion but terminating short of the side plates.

5. A car roof comprising side plates, roof sheets extending from side plate to side plate and having their ridge portions substantially flat and the portion between said ridge portion and each eaves broken conformably to the established tunnel clearance outline, said sheets having, at their side margins, upstanding flanges that extend from the sides of the flat ridge portion to near the eaves, channeled carline members below gaps between the adjacent sheets along said ridge portions and having an upstanding side portion between adjacent sheet flanges with its top substantially flush with the tops of said flanges, welds filling said gaps and opposite said edges anduniting adjacent sheets together and to the carline members to the body portions of the intervening carline members, and additional welds uniting the other side portions of said sheets.

6. A` car roof sheet comprising a ridge portion which is substantially iiat for a width-substantially equal to the horizontal top portion of the established tunnel clearance outline and the remaining portions having transverse breaks which conform them to the established tunnel clearance outline for car roofs, said sheet having de-` pressed panels extending lengthwise of the sheet along the middle thereof between the flat ridge o 15 "portion and the respective eaves portions.

8. A car roof sheet comprising a ridge portion which is substantially flat `and the remaining portion'slhaving transverse breaks which conform them to the established tunnel clearance outline for car roofs, said sheet having depressed panels extending lengthwise of the sheetalong the middle thereof between the flat ridge portionand v eaves portions, said sheet having a channelshaped carline member with one side welded to the body portionV of the `sheet and with the other side `of the carline member extending upwardly and projecting laterally beyond the side edge o of the sheet. l

` 9. Afcar roof `sheet comprising a ridge portion which is substantially iiat andthe remaining portions having j transverse breakswhlch conform them to theestablished tunnel clearance outline, and flanges along their side margins,

10. A car root sheet comprising a ridge portion which is substantially flat, portions which slope downwardly on opposite sides of vsaid ridge portion and terminate in downturned `vertical ilanges, and upstanding side marginal flanges that extend along said sloping portions only, said side flanges increasing in height for some distance inwardly from said downturned flanges so that the `tops of the side flanges substantially follow the slope of the established tunnel clearance outline.
