URGENTLY need your help!

Dear Friends,

Would you please URGENTLY help me to find some research papers (up to
three) for following subject? If you could send me it's address (URL
or journal name) I would be so grateful.
As you know, in railroad design, there is a relation between curve
radius (radii), track length and track dimention (cross section). I
would like to find some papers with a subject close to what I
described. Please kindly send your e-mails directly to my adress
which is: [email protected]
Again thank you so much for your guide and help.


With the best regards.
