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.

Not the same turnout. In your example the radius is 232.32 in mine 205.13.
(BRT V08.11.07.685, on MS, SS 2)
It's simple geometry... From 1. to 0. of turnout for radius 232.32 I have 13.6187m. 2*13.6187+6*8.5=78.2374 in your picture is 78.237. In my case the distance from 1. to 0. for radius 205.13 is 12.025, therefor 2*12.025+6*8.5=75.05m. --- Check your source ;)
I am a track construction engineer and it is my dream to do this kind of advanced level work that you are doing. I would be thankful to be able to get in touch with you. Thanks
