The North-South metro construction required several new technologies in the fields of civil, electrical, signaling and telecommunications engineering. Indian engineers backed by their own experience and helped by their studies abroad, used the following advanced technologies for the first time in India:


All the new lines were constructed by the new state-of-art technologies. Most of the new links are elevated with only a few being underground. Unlike the North-South Corridor which used the cut-and-cover method for the whole underground route, the tunnels of the new lines were constructed using a tunnel-boring machine (TBM).
