Work out cant and superelevation instantly with clear inputs, formula shown and shareable results.
Equilibrium cant is the superelevation that exactly balances centrifugal force: gauge times v squared divided by radius times g. Real track is canted less than that, and the shortfall is the cant deficiency, which is limited (often 110-150 mm) because it becomes the lateral force passengers feel.
Cant
equilibrium cant = G x V^2 / (R x g); deficiency = equilibrium - actual cant
Rail results are planning estimates only. Verify against the infrastructure manager's rule book, approved braking curves and applicable railway safety regulations.
Because trains run at different speeds. Full cant for the fastest train would make slow or stopped freight trains lean uncomfortably and load the inner rail heavily.
The opposite case: actual cant greater than equilibrium for a slow train, which overloads the low rail and accelerates wear.
