P-Way Design Calcs.
Three iOS apps for permanent way design. Network Rail L2/TRK/2049 compliant. Built by engineers who use them daily.
P-Way Horizontal Design Calcs
Horizontal alignment calculations for UK standard gauge (1.435m). Cant, curvature, transitions, slew.
App Store →P-Way Vertical Design Calcs
Vertical alignment, gradient, and vertical curve calculations to L2/TRK/2049 §B.4.1.
App Store →P-Way Horizontal Design (1.6m Gauge)
Horizontal alignment for Irish broad gauge (1.6m / 5'3") — Iarnród Éireann.
App Store →Why we built them
Spreadsheets are easy to corrupt, hard to audit, and a pain to share. We built these apps because we wanted a tool that gave us a single, defensible, auditable answer for every parameter check.
Compliance
All three apps are validated against Network Rail L2/TRK/2049 standard sheets, with worked examples cross-checked against spreadsheet references. The 1.6m gauge variant follows Irish Rail CCE-TMS-310.
