(Sofija -) Svilengrad BDŽ - Ormenio OSE- Díkaia/Díkea (- Píthio)
[D] OSE operated one train each way between Díkaia/Díkea and Svilengrad but this was withdrawn in August 2009. No service was reinstated when other cross border routes resumed following a period of discontinuance of all international services from Greece from 13 February 2011.
(Sofija -) Kulata BDŽ - Promachon OSE (- Strimon - Thessaloniki)
[D] OSE works to Kulata. The Sofia - Thessaloniki service (including the night train) ceased from 13 February 2011 as part of the discontinuance of all international services from Greece.
The service was reintroduced from 10 May 2014, but from 25 May 2017 Thessaloniki - Sofia - Thessaloniki services were a bus between Thessaloniki and Strimon, and are shown as bus in the 2019-2020 timetable.
However the Redcap at Strimon confirmed that the summer only overnight service from Thessaloniki via Sofia to Bucharest and vice versa ran as a train throughout in 2018 and is shown as doing so in 2019.
