How about the granite ones? I would like to know how that house on Route 117 in Weston near Hastings station got that one in their backyard that is clearly visible from the street. They have to be about 1000 pounds.
Whats the number on it? A number of years ago there was a tribute to the late rail photographer Arnold Wilder in the B&M Bulletin. One photo depicted a grinning Wilder and cohort standing beside a milepost on a recently abandoned line, with shovels. In the background was a flatbed truck. It can be done, its just tedious as hell.
The granite posts don't have the need for steel reinforcement, besides, steel and granite have different coefficients. For an example of what happens when you combine the two and factor in freezing temperatures, visit the little park on the corner of Market and Shattuck in Lowell, and check out the granite posts there.
