The current R&R has an article on the Laona and Northern which says they are going to replace the 60# rail with 90# rail, 2 miles worth. They have a grant for it, but no timing was stated. If anyone is in northeastern Wisconsin this season, it would be cool to check this out. For reference, 56# and 60# rail is between 3 7/8 and 4 1/8 inches high. Dale Reynolds, Pendleton SC
