Answer 2

The correct answer is option C) 6.7m to 7.3m

• A single-track railroad is a railroad where trains going in both directions share the same track.

• The single track is typically found on less-used railway lines, often on branch lines where traffic levels are not high enough to justify the cost of constructing and maintaining a second track.

• The conversion of a single-track railroad to a double-track is called doubling or doubling; the conversion from double track to single track is called singularization.

• A two-track railway that only runs on one track is referred to as a one-way operation.

• This involves the construction of three main types of track: tangent track (straight line), curved track, and track transition curve (also known as transition spiral or spiral), which creates a connection between a tangent track and a curve.

• Various engineering studies carried out for The choice of route for a new railway line survey can be roughly divided into three categories.

• Reconnaissance Survey: This is conducted in two categories namely Traffic Reconnaissance Survey and Engineering Reconnaissance Survey

• Preliminary Survey: Based on the preliminary reports and the traffic survey, the railway administration decides whether the planned railway line will be built or not.

• Final site study: Once the decision to build a specific railway line has been made, a final site study is carried out.
