A railway siding is to be curved through a certain angle which is shown in the figure, in order to avoid buildings. The curve is to be compound, and radii of the two branches are 240 m and 360 m. The distance from the intersection point of the end straight to the tangent point at which the 240 m radius curve leaves the straight is 270.59 m. From the given figure. a. Determine the second tangent length of whole curve. b. Compute the length of the compound curve and the length of the long chord. c. If the Station of the PC is Sta. 1 + 060, determine the Station of PT.

A railway siding is to be curved through a certain angle which is shown in the figure, in
order to avoid buildings. The curve is to be compound, and radii of the two branches are
240 m and 360 m. The distance from the intersection point of the end straight to the
tangent point at which the 240 m radius curve leaves the straight is 270.59 m.
From the given figure.
a. Determine the second tangent length of whole curve.
b. Compute the length of the compound curve and the length of the long chord.
c. If the Station of the PC is Sta. 1 + 060, determine the Station of PT.
