Railways & metroHSR, metro, dedicated freight corridors

Heavy-rail network expansion, high-speed rail, urban metro/RRTS and dedicated freight corridors, including civil works, track, traction power, signalling (CBTC/ETCS/Kavach) and rolling stock. Rail is among the worst reference classes for cost (mean overrun 39%, Flyvbjerg 2026) and ridership (urban rail ~51% below forecast). India runs the largest programme (MoSPI: 246 rail projects, original INR 6.91 lakh cr revised to INR 8.42 lakh cr, +21.9%), while HS2, California HSR and Rail Baltica illustrate Western escalation.

Regional notes

India	Largest rail capex programme globally (Indian Railways plus 21 metro systems, MAHSR, DFCs, RRTS). PAIMANA Mar 2026: railways +21.9% revised vs original; urban public transport (26 projects) +6.9%. Capibud parse: 46% of rail projects delayed but long original timelines (median 99 months planned) mask slippage; metro/urban projects 72% delayed.
United States	IIJA USD 66bn for passenger & freight rail; administration hostile to CAHSR (grants terminated Jul 2025) while private Brightline West proceeds at USD 21.5bn; Class I freight railroads self-fund ~USD 20bn+/yr capex (estimate).
Europe	TEN-T core 2030 deadlines; HS2 (UK) re-baselined May 2026; Rail Baltica funding gap; Grand Paris Express slippage; CEF co-funding and EIB lending.
Middle East	Riyadh Metro, Etihad Rail and Gulf HSR plans; 2026 war raises security and financing risk.

Revenue model

Fare-box plus non-fare (advertising, property/TOD) revenue for metros/HSR; track-access and freight tariffs for DFCs; most projects are publicly funded with concessional loans, VGF or availability payments; private role mainly EPC, rolling stock and O&M.

How Capibud uses this pack

A pack is a starting position, not a forecast. When a railways & metro decision opens in Capibud, pack v1.0.0 is copied in and pinned to that decision. The 13 parameters, 12 swing factors and templates the committee saw stay attached to the decision record, even after the pack is next refreshed.

Parameter ranges and WBS durations seed the P50, P80 and P90 for capex, schedule and value. Your own estimates, vendor quotes and actuals replace pack defaults line by line, and the record shows which numbers are still defaults.

Each swing factor is wired to shared factors; here the heaviest are policy, labour, construction materials and electrical equipment. A move in one factor hits every exposed project in the same scenario, which is how the capital committee sees concentration across a book rather than project by project.

The 14 price feeds and 22 listed tickers feed the brain, which watches for drivers moving outside their pack range and drafts the change for a person to review.
