Hello,
I designed reverse curve with transitions. Curve no 1 is 350m radius and Curve no 2 is 1000m radius. Station is coming over curve no 2. As per Schedule of Dimension norms, Super elevation should be 0 mm at station location. So cant gradient for curve number 2 is completely zero. When comes to curve number 1 to allow 75kmph i have provided 105mm cant. Cant gradient is coming 1 in 590 with 62m transition.
I heared somewhere that cant gradient should be almost equal or there should be very minimum difference. In my case curve number 1 has 1 in 590 cant gradient and curve two has no cant and cant gradient.
My doubt is, Can we provide like that or how does it effect on riding of train..?
Please anyone give the clarification on this.
