A spiral 80m long connects a tangent with a 7° 30' circular curve. If the stationing of the T.S. is 10+000, and the gauge of the tract on the curve is 1.5m. Determine the following: (a) the elevation of the outer rail at the midpoint, if the velocity of the fastest train that can pass over the curve is 60kph, (b) the spiral angle at the first quarter point, (c) the deflection angle at the end point, and (d) the offset from the tangent at the second quarter point.

Curve setting

A curve is a turn that is provided horizontally or vertically in the design of highways, railways, and runways. A curve connects two straight lines that are separated by the deflection angle. It helps to change the direction and alignment of the highways, railway tracks, and runways. Therefore, the gradual change in their alignment is made by using a curve to provide comfort to the passengers and this also provides an easy turn to change the direction of the moving vehicle.
