• Turnout on a spiral

    Hi Friends I have a question about designing turnouts on an spiral / transition curve with cant applied. We have a case where we need to replace 2 turnouts and a connection, with 2 new turnouts and a connection. We can't move the turnouts location…
  • How to Design Reverse Transition

    Dear, I am trying to connect in 2 different radii curve with reverse transition with same langth, how to design id any one give me solution on this. Curve no 1 : R= 126.025 ( Trailing Transition required 25 m) Curve No 2 = 152.075 ( Leading Trans…
  • Re: How to Design Reverse Transition

    Hi, A simple construction could be: Add a fixed radius R126.025 trailing transition L=25m Add a floating radius R152.075 leading transition L=30m: pick the first radius as the element to connect to But it depends on constraints. Regards…
  • Re: Equilibrium constant, equilibrium cant and spiral equation

    Hi Mike, Rumah Makan Padang is still the best ya? I am using new Bentley Power Rail Track Select Series 2. I just want to confirm that the spiral type mentioned in PRT is the same with other spiral type. Based on my reference: 1. Clothoid…
  • Adding transitions to simple curves

    Using Bentley V8i with Rail Track. I did a short layout for a main line track using simple reverse curves. I want to add transition spirals to the curves, but must the length of spiral and tangent length between curves is prescribed by the railway design…
  • Re: A simple parabola transition...

    Hi, I've recently tested the various methods aviable in BRT (V8i series 2). See the attachement. It seems that WA method is the closest to your expectations ;) Altough, as u said, u can always use the clotoid for your transition curve. WS
