03. For a 2° curve on a high speed Broad Gauge (BG) rail section, the maximum sanctioned speed is 100 km/h and the equilibrium speed is 80 km/h. Consider dynamic gauge of BG rail as 1750 mm. The degree of curve is defined as the angle subtended at its center by a 30.5 m arc. The cant deficiency for the curve (in mm. round off to integer) is

Question The maximum speed on a BG main track if 100 kmph. The track meets a circular curve of radius 275m. The super elevation to be provided is (in cm).
A vertical curve joining a (-5%) and (+3%) grades in a rural highway has a design speed of 100kph. The tangents intersect at a station (225+71.35) at an elevation of 290m. Caleulate the elevations of intermediate points on the curve each 100m, and determine the stations and elevations of PVC, PVT. It s important to know that the driver acceleration rate is 3m/sec2 and the perception & reaction time is 2.5 seconds.
