250+ TOP MCQs on Railway Project Survey and Answers

Surveying Multiple Choice Questions on “Railway Project Survey”.

1. Which of the following is not a stage of railway line survey procedure?
a) Marine survey
b) Reconnaissance survey
c) Selection of good alignment
d) Preliminary survey
Answer: a
Clarification: Railway line surveying involves various important steps like reconnaissance survey, selection of good alignment, preliminary survey, marking of tentative alignment and finally survey report.

2. Reconnaissance survey is done in case of railway line alignment.
a) False
b) True
Answer: b
Clarification: Reconnaissance survey is a study of entire area which may be a land, road or an air field. The purpose of this is to eliminate the sides which are unfeasible, which is important in case of railway alignment.

3. Which of the following must be considered while laying an alignment?
a) Tectonic plate movements
b) Terrain
c) Line of sight
d) Population
Answer: d
Clarification: Laying of alignment for a railway line involves various considerations like population, bridges, and tunnels, gradient and contour of the area. It also involves a deep study of in and around the area of consideration.

4. Alignment considered must be _________
a) Wide
b) Long
c) Short
d) Broad
Answer: c
Clarification: The determination of alignment will play a major role in determining the railway line. The alignment considered should be as short as possible in order to avoid further complications and also we can extend any further if required.

5. While designing an alignment number of curves should be more.
a) False
b) True
Answer: a
Clarification: The alignment considered for a railway line must be as straight as possible and the number of curves must be minimized. This is so because the provision of curves leads to overturning of the train.

6. Which of the following is used while selecting an alignment for railway line?
a) compass
b) Traversing
c) Theodolite
d) Soil survey
Answer: d
Clarification: The selection of alignment for railway line requires information like water table level, Soil survey, Determination of magnetic bearings, Culverts and gradients. All of these are used and are required in each and every aspect of designing.

7. Which of the following comes under the preliminary survey of the railway line?
a) Establishment of R.L
b) Establishment of bench marks
c) Establishment of station points
d) Establishment of intervals
Answer: b
Clarification: The preliminary survey of the railway line consists of several steps like cross level interval, Magnetic bearing, Route survey map, Establishment of bench marks, bearing capacity of soil and water table level.

8. Which process must be adopted before selecting an alignment?
a) Compass survey
b) Traversing
c) Preliminary survey
d) Theodolite survey
Answer: c
Clarification: The selection of alignment requires certain preprocessing method like preliminary survey, which is done for obtaining the good alignment without any error.

9. The final survey report consist which of the following?
a) Angles
b) Bearings
c) Alignments
d) Revenue of the project
Answer: d
Clarification: Final survey report is done after the selection of final alignment. The report includes the introduction of the project, necessity of the project, justification of the alignment selected, revenue of the project etc.

10. Along with the final report which of the following are to be attached?
a) Culverts
b) Route survey map
c) Instrument details
d) Bearings
Answer: b
Clarification: Besides the final survey report some maps with suitable scale are to be attached. Those include route survey map, longitudinal section of the alignment, map of the station yards and the drawings of culverts buildings etc.

11. While doing final alignment survey, which of the following must be taken into consideration?
a) Level crossing
b) Angles
c) Gradient
d) Bearings
Answer: a
Clarification: The final alignment survey involves certain proceedings like fixing of station yards, level crossing, bridge provision places, tangents of the points of curvature and compensation of properties.

12. While handling railway line project, which factor must be given first priority?
a) Plan of the project
b) Nearby areas
c) Alignments
d) Economic factor
Answer: d
Clarification: During the construction of any project, economic factor must be given first priority since it can decide future of any project. The material selected while construction will determine the economy of the project. In case of railway line project, the length of alignment will determine the cost of construction.

13. Which of the following will be used in case of a reconnaissance survey?
a) STAAD Pro
b) Revit
c) Aerial photographs
d) GIS
Answer: c
Clarification: Reconnaissance survey involves studying of the area whether it may be road or air field the output of this survey will determine the feasibility of the land. The usage of existing maps and aerial photographs can act as an added advantage.

14. The alignment selected can be certified as good if __________
a) Less number of vertical curves are present
b) More number of vertical curves are present
c) Less number of gradient curves are present
d) More number of horizontal curves are present
Answer: a
Clarification: The certification of the good alignment can be done on the basis of certain factors like economic factor, earth excavation factor, presence of less number of vertical curves and the location of station yards.
