Financial Tribune - In an ambitious initiative to provide Tehran�s residents with extensive and decent transportation services, four new lines have been designed for expanding the capital city�s subway network.

Tehran Municipality announced that in collaboration with a French engineering and consulting group and the Iranian engineering group Gueno, four additional lines have been mapped for Tehran Subway.

Currently, the capital's subway stretches over 220 kilometers and comprises seven lines (1 to 7) with nearly 120 stations. Line 6 and 7 are yet to become fully operational. The operating lines move through diagonal paths, connecting north to south and west to east of the city, all crossing the central parts.

TM says the new lines (8 to 11) have been designed to cover the areas not covered by the metro network so far.
