List of Belgian railway services

This is an index of all passenger rail services operated in Belgium.

Passenger rail services in Belgium are operated by NMBS/SNCB.

The Belgian rail network is organised into three main domestic passenger train categories on the main lines, these are:
 * Intercity (IC) trains–An express, limited-stop service, often calling only at major railway stations; in some cases it has stops at all stations along part of the route.
 * Local (L) trains (Lokale treinen / trains Locaux)–A local service calling at all stations along the route.
 * Regional (S) trains–A suburban service calling at all stations along the route.

To cater for the large number of commuter workers, especially into Brussels, complementary peak-hours trains run on mornings and late afternoons of working days, they are classified as P trains.

The Brussels S Train service was added in December 2015 and took over a good deal of the L trains. S Trains, and were later also introduced around other key cities like Antwerp, Liège, Gent.

International (high speed) services operate to countries such as the Netherlands, France, Germany, Luxembourg, Austria and UK. These are operated by Eurostar, NS International, Deutsche Bahn, ÖBB Nightjet and SNCF.

Below the train services are arranged by type, and for each type ordered by number. All services are correct to May 2020.
