1) Traffic survey
Traffic survey includes a detailed study of the traffic conditions in the area.
Traffic surveys are normally undertaken in conjunction with reconnaissance or preliminary engineering surveys so that the technical feasibility and relative costs of alternative proposals can be formulated. The traffic survey team should work in close cooperation with the engineering survey team. The survey team should visit all trade centres in the area and consult local bodies, state governments, and prominent citizens regarding trade and industry and propose the most suitable alignment for the new line.
traffic survey team should make an assessment of the traffic likely to be carried by to the new line. While carrying out the survey, details of traffic likely to be offered by various government organizations, public bodies, or private enterprises should be gathered.
At the end of the survey, a report should be formulated by the officer-in-charge of the survey. The formation of the report is governed largely by the nature of the terms of reference and the investigations made. The traffic survey report should normally contain the following information:
(a) History of the proposal and terms of reference
(b) General description
(c) Potentials and prospects
(d) Industrial and economic development and traffic projections
(e) Population projection and volume of passenger traffic
(f) Existing rates and rates to be charged
(g) Location of route or routes examined, alternate routes, and possible extensions
(h) Station sites and their importance
(i) Train services, section capacity, and various alternative ways of increasing capacity
(j) Coaching earnings
(k) Goods earnings
(l) Working expenses and net receipts
(m) Engineering features
(n) Telecommunication facilities
(o) Financial appraisal
(p) Conclusions and recommendations

5) Final location survey
Once a decision has been taken for a particular railway line to be constructed, a final location survey is done. The instruments used are generally the same as in the case of the preliminary survey. Final location survey is done to prepare working details and make accurate cost estimates in certain cases. The principal differences between the preliminary survey and the final survey are as follows.
(a) In the final location survey, the alignment is fully staked with the help of a theodolite, whereas it is not obligatory to
do so in the case of preliminary survey.
(b) In the final location survey, a more detailed project report is prepared and submitted.
(c) All working drawings are prepared in the final location survey.
The following tasks are carried out in the final location survey.
(a) The centre line is fully marked by pegs at 20 m. At each 100 m, a large peg should be used.
(b) Masonry pillars are built at tangent points of curves and along the centre line at intervals of 500 m.
(c) Longitudinal and cross levelling is done to ascertain the final gradient of the alignment. All gradients are compensated for curves.
(d) The sites for station yards are fully demarcated.
In the final location survey, the following set of drawings is prepared.
(a) General map of the country traversed by the project at a scale of about 20 km to 1 cm Index map, scale about 2.5 km to 1 cm
(b) Index plan and sections
(c) Detailed plans and sections
(d) Plans and cross section
(e) Plans of station yards
(f) Detailed drawings of structures
(g) Plans of junction arrangements
5.1) Objectives
The following broad objectives should be kept in mind when selecting the best possible alignment in the final location survey.
(a) Correct obligatory points
(b) Easy grades and flat curves
(c) Minimum cost of construction
(d) Minimum adverse effect on environment
(e) Ease of construction
(f) Potential for high speeds
(g) Avoidance of constraints for future expansion
(h) Minimum maintenance cost
5.2) Project Report
A final project report is prepared based on the final location survey. The report consists of the following.
In this segment of the report, the following details are covered.
(i) Object of investigation and background
(ii) Programme and methodology of investigation
(iii) Special features of investigation
🔸Characteristics of the Project Areas
In this segment the topographical outline of the areas and geographical features of the country are given to the extent to which these are likely to affect the alignment, probable stability of the line, cost of construction, working expenses, or future prospects of the proposed line. Climatic and rainfall characteristics and environmental characteristics such as the presence of corrosive factors, pollution, etc., which may have an effect on the design and maintenance of structures and bridges, are also brought out.
🔸Standard of Construction
This segment gives details Gauge, Ruling gradient, Curves, Permanent way, Ballast, Stations, Signalling and telecommunication, Traction and other details such as road crossings, station machinery, residential accommodation, service and maintenance facilities, etc.
🔸Route Selection
This segment provides relevant information and data related to the various alternative routes examined and gives an insight into the factors influencing the choice of the route adopted for the project.
🔸Project Engineering
This section furnishes information and data for the project manager to enable him to understand the scope and extent of the project and to assist him in formulating the strategy for the execution and management of the project. It must focus on the problems likely to be encountered, identify the areas requiring special attention, and place the knowledge and information gathered at the investigation stage for evolving optimal solutions.
🔸Estimation of Cost and Construction Schedule
This segment gives a cost estimate of preliminary expenses, land, formation, bridges, permanent way, station building and residential quarters, road crossings, station equipment, signalling and interlocking, rolling stock, etc. The schedule of construction as well as investment is also given. A network should be developed for projects costing above Rs 5 million.
🔸Project Organization
This section details the organizational structure for the execution of the project, the proposed headquarters of the project manager and other construction officers, as well as the allocation of the various construction activities.
🔸Tabulated Details
The report is accompanied by tabulated details of curve abstract, gradient abstract, bridge abstract, important bridges, stations, machinery, stations, and station sites.
🔸Arrangement of Documents in the Report
All the documents pertaining to a final location survey report should be in the following order.
1. Covering note
2. Index
3. Report
4. A list of drawings accompanying the report
5. Appendices to the report
(a) Historical and geographical aspects
(b) Location report
(c) Rates for construction work

    @all: At this time, the PNR Forum is functioning again, albeit at a greatly reduced volume and efficiency. Refreshing PNRs is a very cumbersome affair. We may expect this to end as well, eventually, as the Govt. tightens these controls further. At IRI, we CANNOT waste any more time on this fruitless...

    There are some minor changes to the PNR Forum: 1. The main PNR feed will only show UN-predicted (by you) PNRs which are coming in. However, if there are replies, the PNR will show and will bubble to the top. Once you predict the PNR, it will go away from the main...
