RailEurope
RailEurope is an all-in-one train search engine across Europe. The easy to use and minimalistic websites lets travelers book train tickets and rail passes, as well as plan your trip using the Trip Planner and Activities widget. Rail Europe partners with a huge variety of high-speed train companies across Europe, including Eurostar, TGV, Italo, and Le Frecce.
Although high-speed trains are their specialty, RailEurope also sells tickets for local and regional trains as well. Besides train tickets, the company offers everything you need to plan your activities in Europe, such as sightseeing passes, public transport cards, and hotel packages. Travelers on the go will be pleased to hear that RailEurope has their own mobile app, which allows you to choose a route, download timetables, and make reservations (if you have a rail pass).
