A 600 meter radius curve is introduced between
straight portions of a Broad Gauge measuring 1750
mm Railway line intersecting- to form a total
deviation of 70 degrees. The speed for determining
the equilibrium cant is fixed at 80 kph and the
maximum sectional speed is 110 kph while booked
speed is 50 kph. The maximum permissible cant and
cant deficiency are 165 mm. and 100 mm.
respectively. On Broad Gauge Cant Excess should
not be allowed to exceed 75mm. Calculate the
Length of transition in meters ( largest value) using
the following equations stated below:
(a) L= 0.008 C, X V
(b) L= 0.008 C, X V,
(c) L=0.72 C
Where : L = the length of transition in metres.
V = maximum pemissble speed in kmph.
C, = cant deficiency in millimetres.
C, = actual superelevation on curve in
