A reverse curve must join Tang $1$ and Tang $3,$ and will have it's PRC on tangent $2.$

The Radius for curve $1$ is $R_1=1854\mathrm{.}864$

A Compound curve will be placed at $P{l}_3.$

Here $R_{3-1}=600\mathrm{.}000m$

$R_{3-2}=800\mathrm{.}000m,$ and

${}_{3-1}=28{22}^{\text{'}}{30}^{\text{'}\text{'}}$

Find the equation of chainage for the system.

Find the length of the offsets for the compound curve; $20m$ Right offset and $15m$ Left offset.

Compute the total deflection angles and chords for the second reverse curve, at the first and last $100m$ stations.
