Rail corridors
Train instead of flight: what the numbers actually say
One page per European corridor: which trains run it, how long it typically takes, and how rail, flying and driving compare in CO₂e — calculated from published factors, with every step of the arithmetic on the page.

Published corridors
Six corridors so far, each with a modelled comparison per person and direction. Rail figures use the electricity grid of the endpoint countries, so a corridor through low-carbon grids scores lower than the same distance through a coal-heavy one.

How these numbers are made
Published factors, visible arithmetic
Rail is modelled from the annual country grid snapshot times 0.09 kWh per passenger-kilometre — a Farleda modelling assumption for electric intercity rail, not a measured energy value for any specific train. Cross-border corridors average their endpoint countries.
Flights use the UK DESNZ 2026 short-haul average-passenger factor of 128 g CO₂e/pkm including the radiative-forcing uplift, applied to the great-circle distance between the airport pair. Cars use 166 g CO₂e per vehicle-kilometre on the routed road distance — per vehicle, not per person.
Every corridor page repeats its own arithmetic in a footnote, including the grid values used. Nothing here is measured, certified or an offset: these are planning estimates with disclosed sources and ranges.
Farleda consumer beta
Plan the corridor, keep the record
Farleda plans European trips rail-first and records a saved plan as a signed calculation record you can check publicly. Public beta is planned for 31 October–31 December 2026; dates are planning targets and are updated openly.
