Evidence first
Official GIS/DEM, asset and safety audit, demand model, preliminary profiles and engineering / hazard screening; Gate 0 and Gate S evidence
Delivery, resilience and safeguards
Decide in stages, preserve the right to stop
The dates are a planning sequence, not a construction promise. Each package moves forward only when its transport value, route, impacts, affordability and operating responsibility are strong enough.
Before railway feasibility
One integrated transport master plan
The first national document should define the mobility problem before selecting a railway alignment. It joins rail, roads, buses, aviation, freight, land use, climate, public finance and institutions in one evidence base.
What it must do
- Map passenger and freight movements, access gaps and network failure points using one national GIS and demand model
- Compare rail, road, bus, operational and no-build options with the same years, prices, demand and appraisal rules
- Set service standards, investment priorities, interoperable design rules, funding limits and a sequenced project pipeline
- Assign ownership for assets, operations, maintenance, safety, data, contracts and public-service obligations
Path to statutory status
What would make this an official-grade master plan
The structure can mirror a government master plan, but official status comes from mandate, authoritative data, appraisal, consultation and formal adoption — not presentation alone.
| Workstream | Included here | Required for official adoption | Decision record |
|---|---|---|---|
| Mandate and ownership | Independent national-access concept | Government decision or terms of reference, lead authority and inter-agency steering board | Formal initiation and named accountable owner |
| Baseline and demand model | Open-source screening and documented assumptions | Approved base year, official asset register, national origin–destination survey, freight interviews and model validation | Signed evidence baseline and reproducible model |
| Spatial and engineering basis | Concept corridors and broad constraints | Authoritative GIS and cadastre, alternatives study, field geology and hydrology, reference design and protected corridor | Preferred corridor with documented reasons |
| Appraisal and public finance | Scenario ranges and order-of-magnitude costs | Comparable CBA and MCA, whole-life costs, annual fiscal model, funding ceiling and independent review | Ranked and affordable investment programme |
| Environment, society and land | Network-level safeguards and risk screening | SEA, project ESIA scoping, formal consultation, land acquisition and livelihood-restoration framework | Consultation response and statutory approvals |
| Law, operations and procurement | Dependencies, gates and institutional roles | Concession and legal opinions, operator and safety roles, service contract, packaging and procurement strategy | Implementable institutional and contracting model |
| Adoption and updating | Public website, evidence register and change log | Published draft, response matrix, formal adoption instrument, KPIs, annual reporting and five-year review | Official version, custodian and revision cycle |
Status: this independent initiative is a structured draft and consultation input. It becomes an official master plan only if the competent public authorities commission, verify, consult on and formally adopt it.
First five years
2027–2031 action programme
This period should buy information, safety and operational gains before committing to a long mountain corridor.
| Year | Primary work | Public output | Decision enabled |
|---|---|---|---|
| 2027 | Create programme authority, data room and independent assurance; audit assets, contracts and safety-critical backlog | Governance charter, data standard, baseline condition map and risk register | Approve only urgent safety works and studies |
| 2028 | National travel survey, freight interviews, service model, official GIS, geotechnical desk study and alternatives longlist | Demand model v1 and integrated transport master-plan draft | Remove clearly weak corridors before detailed design |
| 2029 | Field surveys on surviving options; environmental and social scoping; early R1/R2/R4 service trials | Comparable route profiles, quantities, reference case and consultation record | Gate 0: select the first investment programme |
| 2030 | Design and procure stand-alone renewal packages; agree operations, rolling stock, feeders and financing | Reference designs, procurement plan, fiscal model and public-service specification | Gate 1: authorise funded backbone packages |
| 2031 | Start approved safety and renewal works; update demand from pilots; prepare eastern and Gate S studies | Benefits dashboard, revised costs and independent readiness review | Continue, redesign or stop each package |
Climate and terrain
Screen risks before fixing the route
Turn layers on and off, move the map and inspect the broad screening zones. These areas are signals for investigation, not authoritative hazard polygons.
Drag to move · wheel or pinch to zoom · select a station or line
Concept map — routes are not surveyed alignments
Map limitation: the climate-and-terrain layer is a pre-feasibility prompt based on broad known conditions. Engineering must use official hazard inventories, field mapping, boreholes, monitoring and climate-adjusted design values.
Investigation programme
Surveys required before a preferred alignment
A corridor line on the map is not a surveyed centreline. The following packages must share coordinates, assumptions and version control.
| Package | Minimum scope | Required deliverable | Red flag |
|---|---|---|---|
| Survey, GIS and land | Control network, lidar/photogrammetry, parcels, utilities, protected areas and authoritative borders | Versioned 3D base model and land schedule | Any line shown outside verified domestic/legal limits |
| Geology and geotechnics | Mapping, boreholes, laboratory tests, faults, landslides, portals, spoil and groundwater | Ground model, uncertainty bands and investigation gaps | Long tunnels priced from generic cost/km |
| Hydrology and climate | Catchments, flood levels, scour, debris flow, snow, avalanche, heat, wildfire and climate scenarios | Design events, adaptation options and residual risk | Historic climate treated as future design climate |
| Existing assets | Track geometry, bridges, tunnels, drainage, electrification, signalling, stations and depots | Defect register, load ratings and renewal quantities | Modernisation budget without intrusive inspection |
| Environment and heritage | Habitats, water, landscape, cultural property, archaeology, noise and cumulative effects | Constraints map and avoid–minimise–restore sequence | Mitigation used to justify an avoidable high-impact route |
| Operations and safety | Timetable, capacity, traction, tunnel fire/life safety, rescue, maintenance and human factors | Operational concept, hazard log and emergency plan | Civil alignment designed before service and rescue concept |
Institutions and procurement
Build the client before buying the railway
Weak preparation is expensive: late scope changes, fragmented standards and unresolved land or safeguards become construction claims. The programme needs a capable public client and independent assurance.
| Function | Lead responsibility | Control | Publication |
|---|---|---|---|
| Programme sponsor | Government-level steering body with transport, finance, environment, territorial and emergency functions | Published mandate and conflict rules | Decisions, minutes and gate outcomes |
| Delivery authority | Permanent multidisciplinary client team | Competency plan, cost/schedule controls and common data environment | Programme dashboard and contract register |
| Operator and maintainer | Named operating entity involved before design freeze | Whole-life requirements and maintainability sign-off | Service and asset-performance results |
| Independent assurance | Technically and financially independent reviewers | Design, estimate, safety, environment and readiness reviews | Findings and management response |
| Procurement | Packages matched to market capacity and interfaces | Reference design, risk allocation, bid quality thresholds and change control | Awards, beneficial ownership, variations and claims |
| Dependency | Planning treatment | Trigger before commitment |
|---|---|---|
| Cross-border reopening or new interface | Keep domestic benefits and costs viable without assuming opening dates or through traffic | Binding interstate, customs, safety, access, insurance, operating and financing arrangements |
| Border-adjacent alignment | Use authoritative survey and legal review; show a corridor band, not a false centreline | Confirmed cadastral and jurisdictional limits plus construction-security plan |
| International freight | Model as separate contracted modules, not free demand in the base case | Shipper commitments, paths, tariffs, dwell times, terminal and port access |
| External finance | Compare currency, conditions, procurement rules and contingent liabilities | Affordable fiscal envelope and transparent financing agreement |
| Regional disruption | Design domestic service, emergency access and staged opening that can operate independently | Updated scenario test before every major notice to proceed |
| Public legitimacy | Use factual, non-attributive risk language and publish uncertainty | Consultation record, response matrix and lawful land process |
Decision control
Six gates from concept to operation
A failed gate means redesign, defer or stop. It is not an instruction to improve the presentation until the same project appears acceptable.
| Gate | Question | Evidence required | Possible outcome |
|---|---|---|---|
| 0 · Strategy | Is this the best transport programme? | Master plan, reference case, demand model, constraints and fiscal ceiling | Select, combine, defer or remove corridors |
| 1 · Renewal | Is the first operational package ready? | Asset audit, design, possession plan, service, rolling stock, funding and operator sign-off | Tender a complete package or return to design |
| E · East | Which eastern works outperform service and road alternatives? | R2/R3 structures, slopes, winter demand, bus comparison and operating cost | Rehabilitate, stage, use feeder or stop |
| S · South | Which combination of road, coach, feeder and regional reopening best serves the south? | Comparable alignments, quantities, geology, SEA/EIA scoping, demand, freight and no-long-rail case | No new domestic mountain rail is a valid result |
| F · Investment | Is a section affordable and financeable under downside cases? | Reference design, risk model, annual cash flow, procurement, safeguards and independent review | Notice to proceed, resize, defer or cancel |
| O · Opening | Can the system operate safely and reliably? | Testing, certification, trained staff, rescue, timetable, feeders, maintenance and emergency exercises | Open, restrict service or correct defects |
Core delivery rule: tender only a fully defined, funded and independently reviewed operational section. Civil works, systems, rolling stock, depots, energy, staff, feeders and initial operating support belong to the same decision.
Fix the backbone
Justified R1–R4 renewal, stations and measured service improvements; R3 restoration only after engineering and demand validation
Open interfaces conditionally
Gyumri–Kars, Yeraskh–Nakhchivan and Nrnadzor–Agarak depend on design, agreements, border operations and funding; C1 needs revalidation
Build only passed gates
Access studies may become rail, coach, feeder or road improvements, or be deferred; no fixed Kapan or Meghri railway completion year
South Armenia Access Gate · Gate S
What combination of regional rail reopening, road investment, direct coach and feeder transport gives Vayots Dzor and Syunik the best reliable access? No new domestic mountain railway is an explicit valid outcome.
- Topography and preliminary alignment
- Gradients, curve radii and realistic operating speeds
- Tunnel and viaduct quantities, geology and seismic safety
- Competitive end-to-end journey time
- Passenger and contracted freight demand
- Lifecycle finance, subsidy and affordability
- Environment, climate resilience and emergency access
- Comparison with road, coach, regional reopening and no new domestic mountain railway
The north–south route via Nakhchivan is the Armenian Government’s stated position of 11 March 2026, informed by mountainous terrain. It is a policy position, not this project’s independent proof that every domestic alignment is physically impossible. Cross-border service still requires agreements, infrastructure, access rights and a workable border process.
