Plan overview

Intersection points

Drag any point in the plan view to move it. A next to cant or transition means the value is set automatically from the radius and design speed — clear the box to re-enable it, or type a value to fix it by hand.

Horizontal curve schedule

Vertical alignment

Set curve length L or radius Rv; the other is calculated.

Vertical curve schedule

Existing ground

Paste or load ground levels

Paste or load chainage, level rows to show the ground line and cut/fill in the profile. Applying replaces the ground the profile has now.

Structures & earthwork

Derived from the cut and fill against the ground profile. Load terrain first, or design a route, or import a ground CSV in the Profile tab.

What counts as a viaduct, what counts as a tunnel, and the formation width the volumes are measured over are set on the Structures tab of the Considerations panel.

Before crossings can be worked out

Roads, other railways and watercourses are found by looking up the real world around the alignment, then comparing rail level against the ground at each intersection. That needs the following first.

Corridor features

Roads, railways and watercourses surveyed along the corridor.

Coverage and source

OpenStreetMap coverage of minor roads and field drains is uneven. Treat the corridor lookup as a first pass rather than a survey.

Abstract of cost

Review the priced works and manage component bills, measurements and rates.

Estimate basis

Start a detailed estimate from the design or build separate component bills with measurements, deductions and rate analyses. Search Central Railway USSOR 2021 and CPWD DSR 2023, record your project's zone and local adjustments, and combine the component totals in one summary. Items without a verified rate remain marked for review.

Plan head

Stations & yard layouts

Plan station spacing, loops, platforms and yard layouts.

Station planning basis

Station CSBs (Centre of Station Building) placed near habitable areas, with a halt inserted wherever the block section would otherwise run long. The thresholds this works to — block section length, loop CSL, who is worth a station — are the ones set on the Inclusion and Stations tabs of the Considerations panel, so this panel does not restate them and cannot fall out of step with them.
