Thank you sir for the in-depth analysis of negative cant. As we know that transition curves are avoided at points and crossings. For diverging tracks, if we provide simple circular curves, how can we attain cant/superelevation? Could you please provide an example using a 1 in 12 or 1 in 8.5 turnout?

(11.31) Martin's formula for the transition curve for bg/mg Vmax=4.35(R-67)^.5 km/h for ng Vmax=3.65(R-6)^.5 km/h this is right.

Sir Why we take e(theoritical) to calculate the restricted speed. On main track. why not use e(actual)?
