Home ZOS Zvolen [SK] Duslo 744 709-7 out-shopped

Already some time ago, Slovakia's Duslo a.s. ordered the modernization of two old T 448 diesel locomotives. In June 2016, the designated T 448.0856 and T 448.0523 arrived at the ZOS Zvolen works to be rebuilt into Class 744.7 locomotives: 744 709 and 744 710 (we're still trying to find out which loco has become which exactly). These pictures from July 17th show that at least 744 709-7 has emerged from the ZOS Zvolen works now.


The service numbers of the locomotives follow those of the Slovnaft 744.7s (744 704-708). In Slovakia, no 744 701-703 exist as the Slovnaft locomotives used to be in sequence with the three 744.7 locomotives delivered by CZ LOKO (and predecessors) to Czech customers. However, European Vehicle Numbers allow for overlapping internal vehicle numbers because the locomotives are registered in different countries and thus have different registration numbers. As a result, 744 704-8 and 744 705-5 exist both in the Czech Republic and Slovakia. An overview:


Czech Republic - CZ LOKO and predecessors - 92 54 2:
744 701-4 Unipetrol Doprava
744 702-2 SD - KolejovŠ Doprava
744 703-0 SD - KolejovŠ Doprava
744 704-8 CZ LOKO > Erdemir (TR)
744 705-5 CZ LOKO > Erdemir (TR)


Slovakia - ZOS Zvolen - 92 56 1:
744 704-8 Slovnaft (744 728-7)
744 705-5 Slovnaft (744 953-1)
744 706-3 Slovnaft (744 886-3)
744 707-1 Slovnaft (744 827-7)
744 708-9 Slovnaft (744 731-1)
744 709-7 Duslo
744 710-5 Duslo


Not only the numbers of the locomotives may cause confusion, there are some substantial differences between the designs of both manufacturers now. Originally a Czech project, ZOS Zvolen produced the locomotive for Slovnaft based on the Czech design. But, as could be seen with the CZ LOKO 744.7 locomotives for Erdemir, the design has been updated, featuring elements of CZ LOKO's 741.7 locomotives. However, the Duslo locomotives produced by ZOS Zvolen are still closely related to the original 744.7 design, having, for example, older engines (Stage II instead of Stage IIIa).
