NS International, a subsidiary of the Dutch state-owned railway Nederlandse Spoorwegen (NS), operates international intercity and high-speed connections to various European cities, including Brussels. The "IC Brussel" refers to their Intercity service connecting the Netherlands and Belgium. These trains offer a direct and comfortable way to travel between major cities like Amsterdam and Brussels. As of late 2024, NS International, in collaboration with the Belgian railway company SNCB, is introducing new Intercity New Generation (ICNG) trains on the Brussels-Amsterdam route. These new trains are faster, reaching speeds of up to 200 km/h, and offer amenities like onboard Wi-Fi and power sockets. They aim to significantly reduce travel times and increase the frequency of services between the two countries.

The term "Regional" can refer to different train companies and services depending on the country. In Germany, "Regionalbahn" (RB) is a type of local passenger train that typically stops at all stations on a given line, connecting cities to their surrounding areas. Many RB trains are operated by DB Regio, a division of Deutsche Bahn, but other companies also run these services.
