The 35 inch is 027, the 40 inch is O gauge, measure a single section of either track and multiply by four, as that is what the longer sections of straight track are based on.

I believe that an O27 straight section should be 8.839, or about 8 27/32 inches long, which would make a quadruple straight about 35 3/8 inches. But it seems likely that the rationale for that length has been forgotten, leading to considerable variation, over time and among manufacturers. I have examples varying from 8 3/4 to 8 7/8.
K-Line made long O27 straights of exactly 36 inches, and half-lengths of 18 inches.
