The Platform page describes the architectural possibilities — what the system can be configured as. This page describes the settled products — the named models the SBC programme is built on, ready for manufacture and deployment. Six models today: three viaducts (MMC-VA, MMC-VB, MMC-VC) and three transmission towers (MMC-TA, MMC-TB, MMC-TB Guyed). Together they cover the deployment range from distribution-pole-scale to continental multi-modal corridors.
Three named viaduct models, scaling from single-leg single-deck (MMC-VC) through dual-leg two-deck (MMC-VB) to dual-leg five-level (MMC-VA). All three share the same foundation, segment family, and Megafactory production line — the differences are vertical scale and topside configuration.
The full continental standard. Five integrated service levels — freight (8m), aqueduct (17m), services (26m), hyperloop reservation (37m), maglev (50m) — on a dual-leg viaduct. Carries the full SBC service combination including the transcontinental aqueduct.
The Phase 0 corridor standard. Freight deck at 6m + maglev deck at 17m, with HVDC arms, gas, hydrogen, fibre, and water services on a single dual-leg structure. Stage 1 commissions freight before Stage 2 maglev is built above.
The lightest viaduct configuration. One leg, one deck — variable height from 6m on flat terrain to 100m+ at valley crossings, all from the same segment family. The Phase 0-2 Newcastle–Sydney maglev runs on MMC-VC.
Three named transmission tower models built on a single production unit (4m base, 1m top, single 20" L80 13Cr tubular, standard ATS caisson). Together they cover approximately 99.5% of every continental transmission deployment from 132kV sub-transmission to ±1100kV UHVDC.
Two standard 4m MMC pylons spaced 12–15m apart, structurally coupled by three transverse cross-beams. Used for high-voltage strain towers, river crossings, and heavy conductor loading where a single pylon's capacity is exceeded — up to ±1100kV UHVDC.
The standard single-pylon transmission tower. Covers approximately 80% of every transmission tower deployment from 132kV through ±500kV HVDC. The Phase 0 corridor backbone runs entirely on MMC-TB. Single 20" L80 13Cr tubular, standard ATS caisson.
Standard MMC-TB pylon supplemented by three guy wires from upper pylon points to ground anchors. Reduces base bending moment by ~70%, extending the single-pylon range to higher voltages. For remote and unconstrained corridor segments — outback Australia, mining areas, defence infrastructure.
All six models share the same foundation system (Anchor Tension System — ATS), the same modular precast segment family, the same drilling rig fleet, and the same Newcastle Megafactory production base. The differences across the family are configuration choices, not architectural ones — leg count, deck count, segment count, topside fitting. The Megafactory produces standard parts; the models are different assemblies of the same parts.
This is what makes the platform productised rather than bespoke. A nation deploying MMC-VC for a maglev passenger spur, then MMC-VB for a freight corridor, then MMC-VA for a continental multi-modal trunk uses the same factory, the same workforce, the same supply chain. The sixth deployment costs less per kilometre than the first because the production base is shared across all of them.
Each model is described here as a settled product — its specification, dimensions, configuration, and deployment range. The engineering memos that describe how each model works are catalogued in the Library. The deployments where each model is used are catalogued in Projects. Models is "what we make"; Library is "how it works"; Projects is "where it goes."
