Which one of the following alignments is obtained by development
accompanied by tunneling?
(a) Valley alignment
(b) Cross country alignment
(c) Mountain alignment
(d) Zig-zag alignment
(C)
The alignment of a tunnel constructed as part of a development project would depend
on various factors, such as the topography of the area, the geological conditions, and
the tunnel's purpose. A zig-zag alignment would not typically be used in tunnel
construction, as it would increase construction costs and complexity without providing
significant benefits. A "Mountain Alignment" typically refers to a tunnel alignment that
follows the contour of a mountain or hill. This type of alignment is often used when a
tunnel is needed to bypass a mountainous area or provide access to resources within
a mountain. However, it is important to note that the alignment chosen for a tunneling
project would depend on a wide range of factors, such as the area's geology, the
presence of other infrastructure, and the project's specific needs.

of axles should be rationalized.
iv. Rail-to-sleeper fastenings i.e., elastic fastenings for different types of sleepers at
high speeds should have definite standards.

Question-Answer:
In Map versus Aerial photograph, due to
symbolic representation the clarity of details
is
(a) less on map than on a photo
(b) more on map than on a photo
(c) less on a photo than on map
(d) more on a photo than on map
Ans. (b)
Differences between Map and Aerial
Photograph,
1. The map is an orthographic projection, whereas an aerial photograph
is a central
projection, i.e. perspective projection.
2. The map has a single constant scale, whereas it varies from point to
point depending
upon their elevations in an aerial photograph. In the case of the
photograph, the
terrain area which has higher elevation is closer to the camera and
therefore appears larger than the terrains area laying at a lower
elevation.
3. The number of details on a map are selective whereas in a aerial
photograph there
is a large number of details.
4. Due to the symbolic representation, the clarity of details is more
on the maps than
on photo.
