==Countries with defunct InterRegio services==
===Belgium===
In Belgium, InterRegio (IR) trains were slower than the fast IC trains, and usually called at more stations along a route. Their journey was usually not as long as IC trains, but still traveled further than the local (L) trains. Most IR trains had hourly frequencies, some having only services every two hours (although this is mostly true only for weekend services). All trains in Belgium shared the same cost structure, so taking an IR train cost the same as an IC or L train for the same route. The only difference lay in the number of station stops they called at. In December 2014 the InterRegio was withdrawn, InterRegio lines were either converted to [[InterCity]] or local train or cancelled completely.{{cn|date=August 2024}}

===Germany===

InterRegio trains were also commonplace in Germany from 1988 to 2003. They travelled and mainly connected regions in Germany. Most of the InterRegio lines have been replaced by [[Intercity (Deutsche Bahn)|InterCity]] lines; a few were replaced by the newly established [[Interregio-Express]] (IRE) type. However, Interregio-Express lines belong technically to the short distance train category, and tend to be shorter. InterRegio trains were very popular as they could be used without supplement.

DB gradually retired the concept in favor of more expensive [[Intercity (Deutsche Bahn)|InterCity]] (IC) or [[Intercity Express]] (ICE) trains with several former IR lines also being split up and downgraded to regional services.{{cn|date=August 2024}}

===Italy===
The ''[[Ferrovie dello Stato Italiane]]'' introduced interregional trains ({{langx|it|treni interregionali}}) in 1993, with [[express train]]s and some direct trains classified under this category. The name was abandoned in 2006 and the services subsequently operated as either CityExpress (CExp) or regional trains (R/REG). Since 2010, the former interregional trains received the new category {{lang|it|treno regionale veloce}} (RV/RGV), {{lit|fast regional trains}}.
