SBC Phase 0 — Australia

Melbourne–Brisbane inland corridor.

2,423km. Zero tunnels. Two-leg, two-deck MMC-VB viaduct. Ten integrated services on a single elevated structure. Stage 1 (freight viaduct) commissioned early — generating revenue while Stage 2 (maglev) is built above the running freight line. The first full continental corridor in the Sovereign Build Corporation programme, and the deployment that establishes the Newcastle Megafactory.

Route alignment is indicative. The corridor shown on the project map is a suggested alignment based on the current planning case. Final geometry is subject to detailed engineering — terrain survey, geotechnical analysis, environmental and cultural heritage assessment, and stakeholder consultation will determine the final alignment at detailed design.

Project-specific engineering and policy documents.

Memos directly applicable to Phase 0. System-level memos (Megafactory specification, transmission tower sizing, foundation anchor architecture) are catalogued in the Library; while their reference deployment is Phase 0, the engineering they describe applies to the MMC system across all deployments.

All memos are listed for reference only and are pending publication review. Detail pages and PDFs will be made accessible after each memo's review process completes. To request advance access for partner discussion, please contact the team.

Memo SBC Phase 0 Maglev vs HSRA High Speed Rail. Head-to-head comparison on services, speed, delivery, and sovereign value. HSRA Line 1: 59% tunnels, 1 service, revenue 2038. SBC Phase 0: 0% tunnels, 10+ services. Includes the tunnel question, services multiplier, construction methodology, and sovereign value analysis. Programme-level document spanning Phase 0, Phase 0-1, and Phase 0-2. Cost comparison detail pending review. 7 May 2026

System-level memos that use Phase 0 as their reference deployment.

The following MMC system memos use Phase 0 as their reference corridor for worked examples, module counts, and economics. They describe the MMC platform, not Phase 0 specifically — but the numbers in them are anchored to the Phase 0 deployment.

Library Memo 1 — Megafactory Specification. Reference deployment is Phase 0: Newcastle Megafactory specification, 5.2M modules, 81.5M tonnes concrete, 3 production lines, 10–12 Spoke injection stations along the 2,423km corridor. 7 May 2026
Library Memo 2 — MMC-T Transmission Tower Tension Sizing. Phase 0 corridor uses the MMC-TB single-leg standard for the ±500kV HVDC backbone. Worked examples and tower sizing in this memo apply directly to Phase 0 transmission infrastructure. 7 May 2026
Library Memo 3 — Foundation Anchor Architecture. Standard 4m caisson foundation deployed across the full Phase 0 corridor. Soil and rock requirements include typical NSW corridor geology along the alignment. 6 May 2026

Phase 0 documentation in active preparation.

Additional Phase 0 project documentation is in active engineering development — including the MMC-VB viaduct engineering memo (companion design memo for the dual-leg two-deck Phase 0 configuration), the Phase 0 corridor route specification, the Phase 0 construction methodology and sequencing, and the Phase 0 financial and economic case. These will be added to this project page as released.
