:::I'm not sure I follow your point.  Before I added the names, clicking "Map of all coordinates" at the bottom of the page opened a google maps page, with the stations marked, and a list of "1", "2", "3" down the left side (but, in a different order, I think).  Adding the names, and the same page opens with the station names instead of the numbers, and there is still just one set of points  not two, so, nothing is duplicated.  I looked at a few other pages in , and usage of the name parameter is very common.
