Line D (Rome Metro)
Line D is a potential line of the Rome Metro system. The line has not been approved yet, but there has been a substantial amount of funding and research that has gone into it.[1]
Route
The specific route that the train will run is unclear, but it is likely that it will run from south-eastern EUR section of Rome to the area directly south of the city centre. Then, it will travel parallel to Line B, passing through the city centre, intersecting with Line C at Argentina and Line A at Barberini. Then, it would extend to the northern area of the city.[2] It is also possible that Line D would take over the Roma-Lido train line.
