I think it looks great, didn't mean my comment as criticism at all, was just wondering about how tracklaying goes, and I'm impressed by your work, wish I could try it myself someday!  

By the way, I messed up my calculation, forgot to keep the length unit constant.  So in my example smaller rail of same sectional shape would be thinner by the square root, not the cube root, of the ratio of the weights per yard, so the stiffness of a given length of rail would go as the weight per yard to the 3/2 power, meaning that 40 lb rail would be slightly less than half as stiff as 65:  (40/65)^(3/2)  =   0.48

Cheers,
