The Greenline is a light rail line to be operated in the Tel Aviv metropolitan area mass transit system. The line will connect the southern portions of the Gush Dan metropolitan area (Holon and the outskirts of Rishon Lezion) with the city of Tel Aviv, and serve as the connecting line of the planned mass transit system, providing a solution for future development along the coast between Tel Aviv and Herzliya, and enabling accessibility to the employment centers in Ramat Hahayal, Tel Aviv University, Holon, and Rishon Lezion.
The length of the line is approximately 39km, of which 4.5km are underground, with 61 stations, five of which are underground (the Levinski, Carlebach, Dizengoff, Kikar Rabin/Municipality, and Arlozorov stations).
The southern portion of the line has two branches – the first, the Western branch, begins in Rishon Lezion (Moshe Dayan station), and the second, the Eastern branch, also begins in Rishon Lezion at the meeting of Road 412 with the Blue Line station. The two branches run through the city of Holon along two routes, come together at Sokolov St. in the Holon city center, from where the line continues north through Holon Interchange, along Har Zion Blvd. in Tel Aviv, through the central bus station region and a crossing of the Purple Line at the intersection of Har Zion-Levinsky. From there the line goes underground, through the Carlebach station shared with the Red Line. It continues through Ibn Gvirol St., again meets the Purple Line at the Arlozorov-Ibn Gvirol intersection, and returns above ground before crossing the Yarkon river by way of a bridge crossing the Rokach Interchange and Sde Dov. The line splits at Einstein St. into two branches: One eastern, towards Ramat Hahayal, through Einstein St., meeting the bus lane at the Einstein-Namir intersection, continuing to Tel Aviv University, George Weiss St., crosses Ayalon Freeway, passes near Yarkon Park and the convention center, goes through Ramat Hahayal to Kiryat Atidim. The second branch, a northern branch, continues parallel to the coastline up to the Herzliya industrial zone and the intersection of Abba Eban Blvd. and Naomi Shemer Blvd.
The line has several intersections with other transit lines: it meets the Purple Line at the Levinsky Tel Aviv station and Arlozorov Tel Aviv station, meets the Red Line at the Moshe Dayan station in Rishon Lezion, and Carlebach station, meets the Yellow Line at the Holon Junction and at two other points in the Ramat Hahayal region of Tel Aviv, meets the Blue Line on Road 412 in Rishon Lezion and at the Holon Junction, and meets the Pink Line in Herzliya. Additionally, there is a connection to Israel Train Lines at the Moshe Dayan station in Rishon Lezion, at the Holon Junction, and at the Tel Aviv University stop.
