Corridor service working groups by discipline. The leading manufacturers, infrastructure firms, and engineering authorities in each field that rides on or in the MMC viaduct.
The MMC Consortium is the proposed working coalition to co-author the global standards for continental corridor infrastructure — the viaduct geometry, the maglev electromagnetic envelope, the freight rail gauge and coupler interface, the road structural specification, the HVDC voltage class, the water aqueduct pipe class, the pipeline diameter, the sovereign fibre routing, the hyperloop tube envelope, and the civil construction sequence.
Each working group below covers one service that rides on or in the MMC viaduct, or the civil construction of the viaduct itself. The firms named are the leading global manufacturers, contractors, and engineering authorities in each field at 2025-26 deliveries. Inclusion is not a statement of pre-existing endorsement or commitment from the named organisation. This list is the public reference from which outreach is conducted.
The principle of participation is Apollo–Soyuz architecture: each firm contributes to the shared standard; each firm continues to compete on the rolling stock, equipment, and downstream services that run on it. Cooperation in the standard. Sovereignty in the product.

Public reference. The named firms are the leading global manufacturers, contractors, and engineering authorities in each corridor service at 2025-26. Inclusion is not a statement of pre-existing endorsement, commitment, or agreement from the named organisation.
Outreach in progress. Multi-Modal Corridors will write to each named organisation, in turn, requesting their engineering participation in the Consortium. Firms that respond positively are noted as engaged. Firms that decline stay on the list as candidates — the list records who is competent in each field, not who is currently committed.
The standard is open. Each working group is open to the named firms and to any other qualified national engineering authority, manufacturer, or research institute that brings working knowledge to the relevant corridor service. The Consortium is a standards-authoring body, not a procurement vehicle. Commercial work in each nation continues to be procured by each nation's normal process, against the shared standard the Consortium authors.
If your organisation is named on this list, or your organisation has working knowledge in one of the named corridor services and would like to be added, Multi-Modal Corridors is the point of contact.
