Network and regional access
One network,
Different ways to reach it
Rail is assigned to the strongest corridors. Timed feeders complete access where a new mountain railway would be disproportionate. Every coloured line is a concept until its route, demand and impacts are verified.
Interactive system
Geography and passenger logic
Explore terrain, labelled stations and corridor status. S4 marks the official Gyumri–Akhurik project; international operation remains conditional. Both map formats remain available on the overview page.
Network architecture
Four core corridors and conditional access
Existing infrastructure, restoration, official interfaces and unselected studies have different evidence requirements. No internal mountain railway to Meghri is selected.
| Corridor / group | Geography | Planning status |
|---|---|---|
| R1 · Northern | Yerevan–Armavir–Gyumri–Vanadzor–Ayrum | Core · existing / modernisation |
| R2 · Sevan | Yerevan–Hrazdan–Sevan–Shorzha; Sotk separately gated | Core · existing / modernisation |
| R3 · Tavush | Hrazdan–Fioletovo–Dilijan–Ijevan | Core · historic / restoration after survey |
| R4 · Ararat | Yerevan–Masis–Artashat–Yeraskh | Core · existing / modernisation |
| Regional interfaces | Gyumri–Akhurik / Kars; Yeraskh–Nakhchivan; Nrnadzor–Agarak / TRIPP | Official processes · design, agreements, funding and operations remain separate gates |
| C1 | Fioletovo–Vanadzor | Previously studied connector · revalidation required |
| Access studies | Aragats / former R7; Ashotsk–Bavra / Akhalkalaki; north-eastern Tavush; Bazum crossing and Lori plateau | Mode undecided · rail, coach, feeder, road or defer |
| Earlier mountain concepts | Vardenyats / former S3; internal mountain railway to Meghri | Comparator only · no-build default; no alignment selected |
Engineering screen
Topography before a route
The relief view marks broad constraint zones, not alignments. Vardenyats, Bazum, Vayk–Jermuk, Sisian–Kajaran and Kajaran–Meghri each need surveyed profiles, geology and an emergency-access concept before a rail option can be compared fairly.
03 · Topographic feasibility
Terrain before alignment
A terrain screening layer, not a railway alignment. Broad zones show where relief is likely to drive gradients, curves, tunnels, viaducts, winter operations and emergency-access requirements.
Moderate constraintHigh constraintVery high / tunnel-intensiveTourism demand points · not stations
Why endpoint height is not enough
Similar endpoint elevations do not make a corridor level. The railway must cross every ridge and valley between them; the controlling gradient and tunnel requirement are set by the intervening terrain.
Screening only · replace with official DEM, surveyed profiles, geology and seismic investigations before route selection
New evidence cases
Road and tourism projects change the demand test
Neither case commits a railway. Both change the alternatives and demand that must be tested before R3 or Aragats access is selected.
Dilijan access · road tunnel and restored rail are not substitutes by default
The Road Department reported public consultations on 24 February 2026 for the new Dilijan road-tunnel design. R3 must therefore be compared with the road project on capacity, door-to-door time, capital and lifecycle cost, winter reliability, tourism demand and network resilience.
Road Department · 25 Feb 2026 ↗Aragats tourism growth case
Test Myler, the separate Government-approved Aragats resort project, Aparan growth and winter peak traffic together. Compare rail, express coach, park-and-ride and seasonal shuttle capacity before selecting the mode. Myler and the resort are demand points, not stations.
Regional passports
What changes for every marz
Each passport states what is direct, what needs a timed feeder and what remains conditional. Journey times and station sites still require a national demand model and official GIS.
National access does not mean rails in every valley. A region counts as served only if the railway and its guaranteed feeder operate as one timetable, one ticket and one protected connection. A study corridor does not count as committed access.
