==Recent and future changes==
All passenger trains south of Sarajevo were withdrawn from 5 October 2015, to allow for track renewals. Trains still appear in the ŽFBH timetable, but with a footnote saying that they do not run until the construction work is complete. No date is specified for this. As a result, the only lines with passenger train services in 2016 were Volinja (Croatia) to Sarajevo via Doboj and Doboj to Tuzla.
The daily pair from Doboj - Šamac was withdrawn from an unknown date in late 2014/early 2015.
The international train between Sarajevo and Ploče ceased at the December 2013 timetable change, withdrawing services over the Čapljina border crossing.
From 1 December 2012 passenger trains ceased on the Novi Grad - Bihać and Tuzla - Brčko lines. The cross border line from Šamac ŽRS to Slavonski Šamac HŽ also closed and
consequently services have ceased from Srpska-Kostajnica (the junction station north of Doboj) to Šamac ŽRS.
A passenger service was introduced on the Brčko - Gunja cross-border route into Croatia in the 2002/2003 timetable but was withdrawn by the end of the 2009/2010 timetable period.
A number of passenger services ceased during the war (1991 onwards)
: prospects for re-opening are slim though all (except Modriča - Gradačac and Martin Brod - Knin) carry freight traffic:
* Podlugovi - Vareš
* Modriča - Gradačac
* Bihać - Martin Brod - Knin (Croatia)
A new route from Valjevo via Zvornik (in Serbia) to Tuzla (in Bosnia-Hercegovina) was started before the break-up of Yugoslavia. Completion of the Zvornik to Tuzla section was interrupted by the war in 1991 but has since been largely finished. The line carries no regular traffic but has seen occasional SFOR military traffic. Note that this line is shown wrongly, or not at all, on many maps, and actually runs from Rasputnica [= junction] Donja Borina, just south of Brasina on the line to Zvornik Grad, via a cross-border river bridge to Zvornik Novi (where there is a large works) then on to Caparde and Kalesija before ending at Živinice, which is on a freight line south from Tuzla. The Beograd - Banja Luka service was intended to run this way but runs instead via Šamac (see above), possibly because of the SFOR traffic and poor track condition on the ŽS (former JŽ) line between Ruma and Zvornik. Work on the Valjevo to Zvornik section was stopped - some construction work can be seen at the Valjevo end - but there are plans of a restart using EU finance. There are optimistic plans by ŽRS to connect the isolated Bijeljina - Velino Selo - Sid ŽS ( former JŽ) line to the Doboj - Šamac line, branching off just north of Milosevac on the Šamac line and running through Brčko to Bijeljina. This would provide a direct link to Serbia, to eliminate the need to cross into Croatia or the Muslim-Croat Federation, and would connect the western and southern parts of the Republika Srpska.
