The first line was a compromise between earlier route proposals further east and west (one of which belonged to the planned Line 4) and as such does not go to some important areas of the city.
Pirma linija buvo kompromisas tarp ankstyvesnių maršruto pasiūlymų: rytai - vakarai (kaip buvo suplanuota 4 Linijai) bet ji neina į kai kurias svarbias miesto sritis.
