RRB Paper · Accepted Answer

Grade compensation for a railway track is given as follows-

For B.G = 0.04% per degree of curve

M.G = 0.03% per degree of curve

N.G = 0.02% per degree of curve

Compensated gradient = Ruling gradient- Grade compensation

Calculation for MG line

Ruling gradient = 1 in 200

Degree of curve = 2°

Grade compensation= (0.03 × 2)/100 = 0.06/100

Compensated gradient = (1/200) − (0.06/100) = 0.44%

Calculation for BG line

Ruling gradient = 1 in 200

Degree of curve = 2°

Grade compensation= (0.04 × 2)/100 = 0.08/100

Compensated gradient = (1/200) − (0.08/100) = 0.42%

Hence Steepest gradient for the BG line = 0.42% and for the MG line = 0.44%

The steepest gradient computed for a 2-degree curve with a ruling gradient of 1 in 200 is done for broad gauge (MG) railway lines. Select the correct inference from the given options.

Steepest gradient for the BG line = 0.44% and for the MG line = 0.42%

Steepest gradient = 0.42% for BG and MG lines.

Steepest gradient = 0.44% for the BG and MG lines

Steepest gradient for the BG line = 0.42% and for the MG line = 0.44%

The correct answer is `No. 4: Steepest gradient for the BG line = 0.42% and for the MG line = 0.44%`
