         Projects for the elimination of hazards, to both vehicles and pedestrians, of railroad-highway crossings may include but are not limited to:
     
    
        
        (1) 
         Grade crossing elimination;
     
    
        
        (2) 
         Reconstruction of existing grade separations; and
     
    
        
        (3) 
         Grade crossing improvements.
     
    
        
        (b) 
         Other railroad-highway projects are those which use railroad properties or involve adjustments to railroad facilities required by highway construction but do not involve the elimination of hazards of railroad-highway crossings. Also included are adjustments to facilities that are jointly owned or used by railroad and utility companies.
