Any "magic incantation" that will just "do this" (for shapefile data) is appreciated. I don't know if copy-pasting the above string into a .prj in the shapefile folder will direct JOSM (via Shapefile plug-in) to "adjust" the data to WGS 84, or if something different is required. It is even possible that clicking on JOSM's alert button of "Yes" is all that is required, but I'm not sure. Thank you in advance.

Well, just clicking "Yes" will definitely not work, since JOSM won't know what to convert from.

I don't know if JOSM doesn't reprojection. But if you want to just do it before loading the data into JOSM and you have OGR/GDAL installed:

ogr2ogr -s_srs EPSG:4267 -t_srs EPSG:4326  output.shp input.shp

I do have OGR/GDAL installed (for this and other reasons!) and have done exactly this before (for example, during my US Forest Service data harmonization in Region 5/California a couple years ago). Thank you, Darrell, for confirming this.

To be clear to anybody else who wishes to use the "Oak Ridge Rail data," a re-projection from NAD 27to WGS 84 absolutely IS required, and one way to do that is to use the ogr2ogr command above. For those new to this, the quickest way is to install GDAL appropriate to your operating system.

Thanks for the quick response!
