Summer-only service from Yerevan to Hrazdan, Sevan and Shorzha[5] (a branch from Hrazdan to Dilijan via the 8km-long Meghradzor-Fioletovo tunnel has not been used since 2012[6] [and onward to Ijevan since 1992[7]]) The latter route is used year round by freight trains, running beyond Shorzha to transport gold ore from Sotk mine just beyond Vardenis back via the Yerevan western bypass freight railway line to the refinery in Ararat (as well as by trains serving the Hrazdan Cement plant located 5km up the Dilijan branch).

A link also exists to the Yerevan Metro at Charbakh Depot via the Karmir Blur siding.

[9] In the ceasefire agreement that ended the 2020 Nagorno-Karabakh War, Armenia and Azerbaijan committed to "unblocking communications" between the two countries.

Since then, the two countries have begun work on restoring the southern railway link, which will go from Yeraskh into Nakhchivan and then cross back into Armenia through Meghri and enter mainland Azerbaijan, connecting to Azerbaijan's main line to Baku via Horadiz.

[10] Normalization talks between Armenia and Turkey since 2022 have also raised hopes that the railway link between the two countries via Gyumri and Kars could be restored, although no agreement has been reached.
