    Title:
    rails.shp
    Railroads of the Former Soviet Union
    Abstract:
    This shapefile contains arcs that describe railroads in the countries comprising the Former Soviet Union. (Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikstan, Turkmenistan, Ukraine and Uzbekistan.) This spatial dataset is available as an ArcView shapefile.
