As I ride more and more of the bike paths here in Rhode Island I discover interesting historical artifacts along the way. Here at the posted coordinates you'll find some remnants of the old railroad when it actively passed thru this area. I think it's great that the designers of the bike path decided to leave some of the old railroad track in place, and in this case even going around it with the path.
To determine the final coords find the leftover railroad equipment that has several dates on it.
A = Day of month in the most recent year listed
B = Last digit of 'E' number
C = Number of dates listed prior to 1900
D = Number of years listed ending in 7
E = Stand number minus 17
F = Number of March dates listed
