Railways is a rail search and planning service that helps travellers compare train journeys across Britain, Europe, Australia, the United States and Japan. Its search experience brings together high-speed, overnight and scenic rail, presenting trips city centre to city centre as an alternative to flying. Travellers can choose origins and destinations, search one-way or return journeys, view popular corridors and indicative fares, and explore destinations on a map. The site also highlights notable scenic routes, including the Glacier Express, Bernina Express, Bergen Railway and West Highland Line, with journey times and descriptions to help inspire trip planning.

Railways offers tools for exploring destinations, planning rail weeks and saving journeys. European journey times are sourced via Transitous, while Swiss departure boards use SBB data. Fares are modelled from typical advance-purchase prices across operators including Eurostar, TGV, ICE, ÖBB, WESTbahn, Frecciarossa, AVE, LNER, Amtrak and JR. Railways is not a ticket issuer; travellers complete bookings through operator websites, where final fares and information are confirmed.
