Question

In order to allow locomotives with a maximum permissible speed of 100 kmph on a BG in transition zone, the degree of curvature will be_____ radian. (Answer correct upto decimal place)

• A. 0.0513

Answer 1

The correct option is A 0.0513
$V_{max}=100kmph$

As per martin formula, maximum allowable speed on BG track

$V_{max}=4.35\sqrt{R-67}$

$100=4.35\sqrt{R-67}$

R = 595.47 m

Degree of curve, $D=\frac{1750}{R}$

$=\frac{1750}{595.47}={2.94}^o=0.0513$ radian
