Question

The mountain alignment can be classified into _________ types.

(a) 4

(b) 3

(c) 2

(d) 1

I have been asked this question in homework.

My doubt stems from Railway Engineering topic in portion Other Major Topics in Civil Engineering of Basic Civil Engineering

Answer 1

The correct choice is (c) 2

To explain I would say: They are the zig-zag development and the switch back development. In the zig-zag developments, the alignments try to follow the contours of the region to an extent. In the switch back, certain contours like steep slopes have to be negotiated and may use buffer stops.
