Along the same lines of this thread I was wondering something, as I am making a Google Earth file marking the milepost on each Sub in the Jacksonville Division, regarding the mileposts & the website fragis.frasafety.net and their mapping of the same. Looking on Google Earth with an imagery date of 12/17/2011 there is a signal tower at MP 664.15 (using the measuring tool on Google Earth). There is a timetable online dated 2005 that states the signal for Highlands is at 665.7 yet there is nothing there. Keeping in mind the mileposts most times are visible and I have been marking them thus. So I haven't been haphazard in my work. For instance MP652 on the Jax Terminal Sub coincides with the visual on Google Earth as well as fragis in relation to the crossing at Yellow Water Rd. So then, following the main line down onto the Wildwood Sub, using that measuring tool in GE, making a path line for 1 mile I come to MP653. There appears to be a tower at that point just inside the North end of Baldwin yard and I presume a MP. Stretching a line from there along that Eastern single track separated from the yard by a tree line I clearly see a MP shadow at 655, 656, 657 then again at 663 ( I don't see one at 654 or any after 657 until 663 but assume, of course, they are there) continuing; 664. I have stopped temporarily at this point attempting to figure out what gives. Additionally I know it is the practice occasionally, for whatever reason, to shorten certain distances between MP but have not found anything in regards. Any insight would be appreciated.
