Each nation plans its network; the spines join them.
Where high-speed or main-line rail already exists — across most of the continent — MMC corridors follow it, upgrading the line or running above it on viaduct, and add freight and services to the same structure.
Routes are indicative. Corridors are drawn city to city, through the cities on the existing railway wherever a line exists: MMC corridors follow those lines, upgrading the line or running above it on viaduct. Where no line exists, the corridor is new build. Final alignments are set at detailed design by terrain survey, geotechnical analysis, environmental and cultural heritage assessment, and agreement between the nations they connect.

Cross-border links are counted separately. Built km = straight-line km × 1.2 (stated assumption).
- Eurasian Spine: Istanbul – Edirne – Plovdiv – Sofia – Niš – Belgrade – Budapest – Vienna – Salzburg – Munich – Stuttgart – Strasbourg – Paris – Channel Tunnel – London, from Peshawar. About 7,400 km straight-line (8,900 km built).
In use: the Channel Tunnel (bored) and the Øresund link (immersed tunnel). Under construction: the Fehmarnbelt immersed tunnel, and the Brenner and Lyon–Turin (Mont Cenis) mountain tunnels. Proposed sea crossings: Gibraltar, Messina, Helsinki–Tallinn, the North Channel, the Åland Sea. Future crossings, the target as technology allows: Scotland to Iceland through the Faroe Islands, and the Strait of Sicily.
