Luxembourg to Durbuy train with CFL

Intercity is a broad classification for express train services that connect cities over longer distances than commuter or regional trains, often with limited stops and comfortable carriages for long-distance travel. The term \InterCity\" originated with British Rail in 1966 for its electrified West Coast Main Line services.Today, \"Intercity\" or \"IC\" is a brand name used by various railway operators across Europe and other parts of the world, including PKP Intercity in Poland, Trenitalia in Italy, and services in countries like Sweden and Ukraine. These trains typically offer both Standard and First Class seating, with amenities such as power sockets and luggage space. While some Intercity services are modern and high-speed, others may use older rolling stock, with speeds generally up to 160 km/h (100 mph)."

Regionalbahn (RB) is a type of local passenger train service in Germany, similar to regional train categories in Austria and Switzerland. These trains typically stop at all stations along a given line, connecting cities to their surrounding areas and serving shorter, regional routes. While many RB trains are operated by DB Regio, a subsidiary of Deutsche Bahn, other private companies also run these services. Regionalbahn trains are a budget-friendly option for regional travel and are often covered by tickets like the Deutschland Ticket.
