Review
Review of the scientific article presented for publication in the journal  
 «Transport of  the Urals»

1. Title of the article: «Occupation» planning in train schedule in the process of transport infrastructure maintenance	
2.Author: Ivanov P.S., The Ural State University of Railway Transport	
3.Article volume 
The article of the volume 10 typewritten pages contains 4 literary sources.	
4. Research area
The article is devoted to «occupation» planning in train schedule in the process of transport infrastructure maintenance.
The article is a theoretical work. The aim of the article is mathematical formalization of combined and shadow «occupation» planning in train schedule. The main idea of the article: keeping technological sequence of infrastructure maintenance and development processes, combine them by time thereby provide the least intervals in traffic.	
5. Relevance
         It is paid special attention to the problem of train delays minimization (from «occupation» providing or trains speed restriction) in transport field.  This issue became relevant as the result of economic market mechanisms implementation in the field because any delays reduce the traffic flow and consequently profit of the company «Russian Railways». 
        Theoretical researches made in this article are quite relevant and correspond to priority directions of field development. 	
6. Scientific novelty 
        The author describing technological consequence of infrastructure maintenance work organization and development connects it with the process of train traffic organization. At the same time dividing technological processes in the least allowable (indivisible) elements combine them by time on «occupation» that can be provided for long and indivisible works of infrastructure maintenance.
      The author introduced a new notion: «shadow occupation» that allowed to detect for  calendar work planning   “occupation” time on several track railways haul while providing the main “occupation” on one of them. 	
7. Structure of the article.  The article is structured, logical and coherent.
	
8. The main results of the research
          The offered body of mathematics allows to correlate technological processes of work performance and train traffic processes organization on «occupation» area for infrastructure maintenance and development. Conclusions correspond to article text. 	
9. Use of literary sources  
 	The author makes reference to sources written by himself in which before there were described similar models.	
10.Design quality 
      The article was written with the use of professional terminological vocabulary, emotionally coloured words are not presented. The article corresponds to the requirements of editorial board.  	
11. Reviewer’s remarks  
         1. There is not given sufficient explanation of author’s term «shadow occupation».
         2. The author doesn’t take into account the fact that «occupation» division always leads to their increase because of total nonproductive “occupation” time increase.  
         3. The author makes references to the articles written by himself and other sources are not analyzed	
12.Reviewer’s recommendations 
            The article is recommended for publication in the journal «Transport of  the Urals».
