InterRegio
open-in-new
<h2 id="denmark">Denmark</h2> <p>The InterRegio system was also introduced to the Danish railways in the early 1990s and became an alternative to the InterCity services, with no seat reservation required. However, unlike other countries, InterRegio trains in Denmark only operates on Fridays and Sundays, to support the heavy flow of passengers that travel on those days. These InterRegio services also have fewer stops than the InterCity services, which goes against the original InterRegio concept of long-distance trains with more local stops. There are no specific rules for the composition for these trains, and both old and new material has been used for InterRegio services. </p> <h2 id="hungary">Hungary</h2> <p>The InterRégió trains were introduced in Hungary on 12 December 2009 (15 years ago) (2009-12-12). InterRégió trains run mainly on regional lines, but their function is national as well. The trains operate along the lines <a href="/facts/S%25C3%25A1rbog%25C3%25A1rd/Ga1YQQrd">Sárbogárd</a>–<a href="/facts/Szeksz%25C3%25A1rd/kKGAEyHu">Szekszárd</a>–<a href="/facts/Baja%2c_Hungary/zRKcVlvn">Baja</a> and <a href="/facts/Kecskem%25C3%25A9t/b9oqdq1t">Kecskemét</a>–Baja–<a href="/facts/Domb%25C3%25B3v%25C3%25A1r/XmPQqDca">Dombóvár</a>.

Since June 2009 there are more interREGIO trains on routes; most of them are available through the whole week, some of them only on weekends.

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 In December 2014 the InterRegio was withdrawn, InterRegio lines were either converted to <a href="/facts/InterCity/lapnMFV6">InterCity</a> or local train or cancelled completely. </p> <h3>Germany</h3> <p>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 Most of the InterRegio lines have been replaced by <a href="/facts/Intercity_(Deutsche_Bahn)/SyP17lWY">InterCity</a> lines; a few were replaced by the newly established <a href="/facts/Interregio-Express/fIlxpS4l">Interregio-Express</a> (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. </p><p>DB gradually retired the concept in favor of more expensive <a href="/facts/Intercity_(Deutsche_Bahn)/SyP17lWY">InterCity</a> (IC) or <a href="/facts/Intercity_Express/TwUF1cHN">Intercity Express</a> (ICE) trains with several former IR lines also being split up and downgraded to regional services. </p> <h3>Italy</h3> <p>The <i><a href="/facts/Ferrovie_dello_Stato_Italiane/USuzwVEE">Ferrovie dello Stato Italiane</a></i> introduced interregional trains (<a href="/facts/Italian_language/YXsmvlQG">Italian</a>: <i>treni interregionali</i>) in 1993, with <a href="/facts/Express_train/4lxgrnd2">express trains</a> 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 <i>treno regionale veloce</i> (RV/RGV), lit. 'fast regional trains'. </p> <h2 id="countries-with-planned-interregio-services">Countries with planned InterRegio services</h2> <h3>Austria</h3> <p><a href="/facts/Austrian_Federal_Railways/hkFKyUNN">Austrian Federal Railways</a> (ÖBB) intends to introduce the InterRegio category for long-distance services on routes that are currently only served by regional trains and routes currently served by long-distance trains only. The introduction is scheduled for December 2025.<a class="footnote-ref" id="fnref:18" href="#fn:18"><sup>18</sup></a> </p> <h2 id="see-also">See also</h2> <ul><li><a href="/facts/Train_categories_in_Europe/WeFnXeuo">Train categories in Europe</a></li></ul> <ul><li>Bodack, Karl-Dieter (2005). <i>InterRegio.
