Cûdahiya Di navbera Asta Teqîn-Delîl AT6 û BT4 de

Rêjeya teqînê ya ji bo Zona A ji ya Zona B kêmtir e; lebê, pola germahiya T6 ji T4 derbas dibe. Di encamê de, ne guncaw e ku mirov îdia bike ku yek ji ya din xwedan asta teqînê bilindtir e.

Rasttir e ku meriv bêje ku her yek li gorî hawîrdorên cûda yên şewat û teqemenî hatine çêkirin.
