Which one of the following relates to the percussion theory for explaining the cause of creep?
Creep is the
Study the following statements regarding creep.
(i) Creep is greater on curves than on tangent railway track.
(ii) Creep in new rails is more than that in old rails.
(iii) Creep is more on steep gradients than on level track.
The correct answer is
The maximum degree of curvature for Metre Gauge is limited to
Cant deficiency occurs when a vehicle travels around a curve at
Cant deficiency is the difference, between the equilibrium cant necessary for maximum permissible speed on a curve and actual cant provided. So if a vehicle travels at a speed higher than the equilibrium speed, cant deficiency occurs whereas if a vehicle travels at a speed lower than equilibrium speed, cant excess occurs.
The compensation for curvature on gradient for Metre Gauge is given by
The shape of transition curve used by Indian railways is
One degree of curve is equivalent to Where R is the radius of curve in metres.
What will be the curve lead for a 1 in 8.5 turnout taking off from a straight broad gauge track?
Approximate value of curve lead
= 2 x number of crossing x gauge
= 2 x 8.5 x 1.676 = 28.49 m
On a single rail track, goods trains loaded with heavy iron material run starting from A to B and then empty wagons run from B to A The amount of creep in the rails
