Pway Calc: Rail Calculator

Cant, transitions, vertical curves, gradient, stressing extension and more. Nine track calcs, on site, in the office, or in the classroom.

PWay Calc puts the calculations used on site, in the office and in the classroom into one place: cant, transitions, vertical curves and gradient. No spreadsheets, no scribbling in notebooks with a phone calculator.

What's inside:

Cant Maximum speed of a curve Stressing extension (CWR) Gradient Transition rate of change Transition design length Vertical acceleration Vertical curve length Track rake

Each calculator uses the formulas and logic used in real design and site work, not a simplified version for teaching purposes.

Free covers the core calculators. Track Essentials adds the common calculations used most, on site and day to day. Track Pro unlocks the full set, built for designers who need everything in one place.

Who this is for

P-way staff, track technicians, and designers who want to check a calculation quickly, on site, in the office, or in the classroom. If you already work with cant, transitions and vertical geometry, this replaces the spreadsheet you're currently using.

What it isn't

This isn't design software and it doesn't replace your standards or your company's approval process. It's a calculation tool, built to be fast and accurate, not a substitute for engineering judgement.

I run The PWay Engineer, a YouTube channel and set of guides for people who work on or want to work on the railway. PWay Calc is part of the same aim: making the technical side of this job clearer and faster to work with.
