Creating Indian Turnouts

Hi everyone,

I am working on Indian turnouts. While creating turnouts (for ex: 1 in 8.5 BG turnout), I have directly loaded the turnout file which was supplied with BRT package. After I create the connection and if I check the turnout radius and total turnout lengths, its is coming around 205.123m of radius and 31.811m overall length on main line (as specified in turnout file).

But as per the standard Turnout drawing supplied by Indian Railways, the turnout radius should be 232.32m, curve length of 27.2062m, straight length of 4.663m  and over all length along main line to be 31.901m.

I have modified the turnout file according to standard values, but if I click VERIFY  in turnout library, it is showing "Turnout definition is Inaccurate".  Also standard lengths are not meeting with the standards.

Please help me with this

 

Thanks & Regards

Santosh

    Hi,

    I am attaching the turnout drawing and turnout (1 in 8.5) calculations as per Indian standards for your reference.

    Your dwg file differs from your hand write data.

    Please follow the calculations. The drawing I have made, is based on the calculations only. It consists of complete cross over between two tracks of 6 m apart. It means if we draw a turnout (1 in 8.5) with between two tracks of 6m c/c distance, the total cross over length should be 75.05m.
    Please follow the calculations part and provide me the solution.

    On my program works fine, I guess you need to be little more accurate.

    This is my settings:

    Try this settings.

    and for radius 232.32

    You can try to add this to your turnout text file:

    [Begin Turnout]
    [Name] = "CO-1:8.5-232.32"
    [Description] = "Indian"
    [Switch Annotation] = ""
    [Crossing Annotation] = ""
    [Display Cell] = ""
    [Type] = "single"
    [Begin Branch]
    [Theoretical .1 to .1] = 0.000000
    [Length Along Mainline] = 31.901000
    [Triangle] = 18.282313 18.282313
    [Ratio at .0] = 8.500000
    [Begin Branch Data]
    27.206863 232.321365 232.321365
    4.663000 0.000000 0.000000
    [End Branch Data]
    [Leading Linear] = "FALSE"
    [End Branch]
    [Turnout Bending Method] = "default"
    [Along Inner Rail] = "FALSE"
    [Along Outer Rail] = "FALSE"
    [Last Element Unbent] = "FALSE"
    [End Turnout]

    [Begin Turnout]
    [Name] = "CO-1:8.5-205.13"
    [Description] = "Indian"
    [Switch Annotation] = ""
    [Crossing Annotation] = ""
    [Display Cell] = ""
    [Type] = "single"
    [Begin Branch]
    [Theoretical .1 to .1] = 0.000000
    [Length Along Mainline] = 31.811000
    [Triangle] = 19.786000 19.786000
    [Ratio at .0] = 8.500000
    [Begin Branch Data]
    24.022508 205.129922 205.129922
    7.761000 0.000000 0.000000
    [End Branch Data]
    [Leading Linear] = "FALSE"
    [End Branch]
    [Turnout Bending Method] = "default"
    [Along Inner Rail] = "FALSE"
    [Along Outer Rail] = "FALSE"
    [Last Element Unbent] = "FALSE"
    [End Turnout]
