SOLUTION

S1. Ans.(c)
Sol. The sharpens of the curve is designated by its degree of curvature.

S2. Ans.(d)
Sol. Coning of wheel is provide
(i) To check lateral movement of wheels
(ii) To reduce wear & Tear of wheels
(iii) To avoid discomfort of passengers
(iv) To avoid damages to the inner faces of rails.

S3. Ans.(c)
Sol. ▭(Versine of curve (h)= L^2/8R )
L = Length of rail

S4. Ans.(b)
Sol.
Gauge Maximum degree of curve
2. Meter Gauge (MG)
3. Narrow Gauge (NG) 10°
16°
40°

S5. Ans.(a)
Sol. Given, R = 300m.
L = 48 m.
Shift (S) = ?
S = L^2/(24 R)
=((48)²)/(24×300)
= 0.32 m.

S6. Ans.(c)
Sol. Given, Degree (D°) = 4°
Total weight of Train (W) = 50 Tonnes
The curvature resistance for BG = 0.0004 WD°
= 0.0004 × 50 × 4
= 0.08 Torne

S7. Ans.(a)
Sol. The ruling gradient is provided for one locomotive train is a following –
Plain Areas → 1 in 150 to 1 in 200
Hilly Areas → 1 in 100 to 1 in 150

S8. Ans.(c)
Sol. ▭(Deflection anlgle (δ)=(spiral angle (α))/3)

S9. Ans.(b)
Sol. The type of transition curve used in India railways, it cubic parabola.

S10. Ans.(d)
Sol. There are following method used to calculate crossing angle-
(i) Right angle triangle method.
(ii) Centre line method.
(iii) Isocele triangle method
