Help calculating jaw angle, bogie/coach

[adryanxu]

Hi, after try to make my own plane in Autocad, after see tutorials in youtube and finally see models with "Blender"... I decide to ask for help.
I know this dates.

Minimun radius of curve 125 meter
Railway with a track gauge of 1,435 mm
Wheelbase (2), 2650mm
Distance between bogies(2) 11000mm (11 meters)

i think, with that, we can calculate what is the maximum jaw angle that blgie takes in relation the coach.
The real locomotive is a Bombardier High speed. (S102)

i would be very agree, i have in my mind how to calculate with autodata, but i am very bad with this slftware, and i try others with the same result.
I hope you understand my english,and i hope dont annoy you for this Offtopic.
Thanks!

On a real coach there are things that limit the angle between the bogey and the car body, in Trainz there is no limit.

thats right, one guy on youtube answer my question.

The simpliest way to solve this task is to draw it in some CAD.
 If you don't have acces to some cad software you can calculate it.
 If you don't need perfect accuracy you can calculate only this way alfa=asin((11/2)/125)=2,522 deg.
 The difference between this value and the correct value (from CAD) is less than 0,001 deg.
 If you need to take into account the track channel width (usually up to 35 mm) the formula is much more complicated and I recommend to use CAD drawing, but the difference from the value above is 0,07 deg only.
