Grand Rail Line — Infrastructure Record

This is the technical record of the Grand Rail Line. For the project history and narrative, see the project record of the same name. This entry documents the line as a piece of infrastructure: standards, route engineering, and operating assumptions.

Track Standards

The mainline is double-tracked throughout — one line each direction — with powered rail placed at fixed intervals on level grade and continuously on inclines. Track bed is a full-width stone foundation, brick-edged, lit on both sides at intervals that leave no dark gaps at ground level. No mainline grade exceeds the standard powered-rail climb without a switchback, and no curve is taken blind: sight lines are cleared at every bend.

Route Engineering

The line follows terrain rather than tunneling, accepting longer routes in exchange for visibility and maintainability. Major engineered features, in order of construction: the Villa cutting east of Savanna Villa; the homestead embankment across the wet plains; and, in phase two, the Scalloped Gulch bridge at the canyon narrows — the largest single structure planned on the network, currently at the pier-design stage.

Network Logic

The mainline is a spine, not a loop. Every district connects by junction or spur, and the design rule is fixed: no district added later may ever be more than one junction from the network. Stations handle passengers and freight separately; see the rail stations and railway spurs records for those standards.

Operating Status

Phase one (Villa to homestead) is graded with track-laying underway. Powered rail supply is the controlling constraint, dependent on foundry gold and iron throughput.

Field Notes

The first test cart ran the graded section on temporary track. Travel time, Villa terrace to homestead survey post: ninety-four seconds. The same trip on foot is eleven minutes. The case for the railway rests.
