I'm surprised at the fact that there is a 6 tracks section near Ankara.
I've posted list of world's longest quadruple tracks below.

Then, I didn't notice that there would be quadruple sections in Turkey, just because even the biggest city of Istanbul don't have quadruple track sections.
If the there will be extension of suburban rail around Ankara, the quadruple track section will be listed on "world's longest quadruple tracks"
