Ashley2771: I've got to confess that I have never been to Dublin. Somehow, I've been almost everywhere around the area, but not in the City! Ok, now that my confession is over, I searched some databases for some info on a railroad yard in Dublin. A summary is as follows:
> The MD&S had a depot in Dublin, but it is no longer in existence, based on info in the Georgia Railroad Stations website;
> Using Topozone.com, a topographic map of the City shows a jointly used yard by GC and NS to be located on the south side of the downtown business district. Using the County Courthouse square in downtown as a referenced start point, proceed 4 blocks south on Jefferson Street, and you should see the yard (or, what isn't left of it!). The yard extends/extended about the length of about 5 city blocks, in a slightly NE - SW direction. Several streets cross portions of the yard and other streets parallel it on both sides.
[Topozone is a great source for getting info on an area prior to on-the-ground searches! Go to the topozone.com website, type in Dublin, GA; when your screen displays a response, click on the blue Dublin; pick out your map size, scale, etc. and click the "Update Map" bar; then use your mouse pad as a target cursor to navigate your direction of movements in wherever directions that you want to go. Just position the mouse pad where you want to go, and click! It's a great way to check out places, or to follow the routes of railroads, both existing and abandoned!]
> Terraserver.com is a very good source of aerial photographs of whatever coverage and scale that you desire. The effective use of this database requires some knowledge of the geography of an area. Unfortunately, the aerial photo clarity in the Dublin area is not too good, but 1993 dated aerial photos confirm the existence of the above-discussed yard.
I've got a hunch that there is some form of a yard still in existence, and maybe even a locomotive posted in Dublin for local work.
Good luck and best wishes!
