    Railway Survey Categories
     
  • To construct anything haphazardly is not engineering. Prior to survey the available maps of proposed area are studied. This helps in fixing suitable alignment facilitate various surveys work. The various engineering surveys which are carried out for the choice of route of a new railway line survey can broadly be divided in to three categories.
  •  
  • 1. Reconnaissance Survey
  • 2. Preliminary Survey
  • 3. Location Survey
  •  
    1. Reconnaissance Survey
     
  • A reconnaissance survey is the first engineering survey which is carried out in territory which has not been previously surveyed for the purpose of laying a new railway line. The main objects of reconnaissance survey are as follows:
  • * To obtain a general knowledge of the whole territory and
  • * To obtain information regarding the salient feature of the territory.
  •  
    Reconnaissance Survey and Information Gathered
     
  • The information are generally gathered in the following two categories
  • 1. Traffic Reconnaissance Survey
  • 2. Engineering Reconnaissance Survey
  •  
    2. Preliminary Survey
     
  • The object of preliminary survey is:
  •  
  • * To conduct the survey work along the alternative routes (found out by reconnaissance survey) with the help of theodolite and leveling instruments
  • * To determine the greater accuracy the cost of railway line along these alternative routes involving cost of removing obstruction, construction of bridges etc.
  • To decide the most economical and efficient route
  •  
    3. Location Survey
     
  • It is the final survey used to locate the centre line of the railway line the main object of this survey is to carry out the detaile3d survey along the route which has been fixed as the most economical route from the data of preliminary survey.
  •  
  • Work of Location Survey
  • The location survey is carried out in two stages
  •  
  • 1.Paper Location
  • 2.Field Location
