In January 2001 the Di 3.619 (Trainkos 005, now in red/redbrown with a yellow stripe in between livery), 633 (Trainkos 006, now in a red with large yellow stripe livery), 641 (Trainkos 007, now in a red with white stripe livery) and
643 (Trainkos 008, now in a red with yellow stripes on the noses livery) were donated by the Norwegian government to the Railways of Kosovo (ROK) as part of KFOR in Jugoslowakia, a division of the United Nations Mission which temporary administrated 330
kilometers of railways in Kosovo. The 005 and 007 are preferred for passenger duties as they are equiped with HEP equipment. Since March 2001 Unmik Railways was responsible for the exploitation and rolling stock for KFOR. Nowadays Trainkos (formerly known as Kosovo Railways) are operating independently. Due to
political trouble between Serbia (which sees Kosovo still as a province of Serbia) and Kosovo (which declared itself independent, recognised by many countries) the railway line between Leshak and
Kosovo Polje is as from Obiliq (freight only) not operational since the beginning of 2008.
Only 007 is operational and worked until March 2017 the following passenger trains if the loco was available:
Tuesday - Thursday with 2 ex-ÖBB coaches, Friday - Monday with 3 ex-ÖBB coaches:
Train IC760 Pec/Peja 05:32 - Kosovo Polje 07:21 - Pristina 07:32
Train TL4201 Pristina 07:50 - Kosovo Polje 08:01 - Pec/Peja 09:57
Train TL4200 Pec/Peja 12:10 - Kosovo Polje 13:59 - Pristina 14:10
Train 4401 Pristina 14:25 - Kosovo Polje 14:35
Train 4402 Kosovo Polje 16:00 - Pristina 16:10
Train IC761 Pristina 16:20 - Kosovo Polje 16:31 - Pec/Peja 18:16
If another roundnose is available, it is used to run nickel ore trains between Medvec and Drenas (train numbers 57860 and 57861), for extra nickel ore trains between Miradi (shunting yard just south of Kosovo Polje) and Drenas (10,000 tonnes of nickel from Indonesia via Griechenland - Macedonia -
Hani i Elezit for the NewCo Ferronikeli plant in Drenas), for freight trains between Miradi (shunting yard just south of Kosovo Polje) and Hani i Elezit/Deneral Jankovic (in relation with Macedonia) and sometimes also coal trains
from Obiliq (Kastriot) to the NewCoFerronikeli plant in Drenas (usually runs every second day). Freight duties are shared with two Class 661 locos, one Class 644 (GT22HW) and one G1700-2 BB loco and the empty coal to Obiliq with two Class MD03 shunters).
The current status of the loco workings in Kosovo is:
005 (now numbered 2640-001, ex-NSB 3619): out of order (engine defect);
006 (now numbered 2640-002, ex-NSB 3633): spare parts loco, not operational;
007 (now numbered 2640-003, ex-NSB 3641): passenger trains 4100 (departure 16:00 from F. Kosovo to Hani I Elezit) and 4101 (departure 17:35 from Hani I Elezit to Pristina) quite regularly.;
008 (now numbered 2640-004, ex-NSB 3643): spare parts loco, not operational.
