yes, the 9V track (with metal top) is available as unofficial file, see
http://www.ldraw.org/cgi-bin/ptreviewsum...aintrack9v
you will get it when downloading all unofficial files
http://www.ldraw.org/library/tracker/
To much more easily layout train tracks, I suggest using software BlueBrick
http://bluebrick.lswproject.com/
which can save files in LDRAW format.
LEGO modified the 9V train track again some years ago to no longer have metal top
but instead be 100% plastic. These are not available in LDRAW yet except for 1 part, the straight rail 53401.dat,
which is an official file since update 2013-02.
