Diesel-electric locomotive
Croatian language - Hrvatski jezik
This locomotive series was derived from the 661
(HZ 2061) series »Kennedy«,
in order to enable operation on the local tracks which supported lesser axle
pressure (because in the meanwhile all the major mainlines had been
electrified). Originally, ten units had been assigned for the reconstruction,
but the project was restricted because of the war. The first reconstructed unit
(646-001, today 2043-001) was assigned to service on 1991/02/13, and the last
one (2043-006) on 1999/02/06.
The reconstruction began with the unit no. 661-101. The aim was to
decrease the overall weight of the locomotive. To achieve the goal, the number
of traction motors was reduced from six to four. Two traction motors were
removed together with the reducers, which decreased the weight from 112 to 99
tons. After the removal of two traction motors, new electric circuits had to be
calculated and installed.
The original steam car-heating system was replaced by electric heating
system, manufactured by Uljanik Works in Pula, Croatia. Now it was possible to
lower the front part (the hood) of the locomotive, where the steam generator had
been originally situated. This allowed the engineers to have a clear view of the
track. The installed power of the new unit has remained the same, but the
traction effort was decreased because of the weight loss.
The unit 2043-004 was derived from 2061-005 (former 661-008); 2043-005 from 2061-004 (former 661-007); and the last one, 2043-006 from 2061-008 (former 661-018).
