Green Line or Line 5 was the first line to be constructed under Delhi Metro’s Phase II. It is also the first line on the system to use 1435 mm (standard gauge) tracks; the electrification is the same as for the rest of the system — 25 kV AC through overhead wires. Like the Blue Line (Line 3/4), the also functions as two individual sections — main line from Inderlok to Brigadier Hoshiyar Singh in Bahadurgarh (26.3 km; 21 stations) and branch line from Kirti Nagar to Ashok Park Main (3.3 km; 3 stations). The section of the line, where it travels above the Punjabi Bagh flyover, ground-level road and underpass, is one of the highest points of Delhi Metro.
