[edit] Prototype
The two units of JŽ 462 (HŽ 1161) series were converted from the JŽ 362 (HŽ 1061) series. The reelectrification of the Zagreb - Rijeka line was planned. The 3 kV DC should be converted to 25 kV ~ 50 Hz. In order to reuse existing roling stock, it was planned to preserve as many existing parts as possible. Also, newly used parts had to be compatible to the JŽ 441 (HŽ 1141). The modified locomotive had also to comply with the technical regulations.
As of the preserved parts, the bogies were reused, the main frame was reinforced. The traction motors and pantographs had to be modified for the higher voltage.
Newly used parts included: the main transformer, new direction switch, new electrical amplifier, new air compressor and some parts of the pneumatic devices.
So, the result is the first six-axle locomotive at Hrvatske Željeznice. The 1061 number was changed to 1161, in order to indicate a new subseries.
[edit] History
- First unit: arravial at Zagreb Workshop on 1980/06/25.
- Second unit: had been waiting at the workshop since 1979/07/28.
[edit] Testing program
On 23rd of March first test drive was performed. The unit was permitted into the traffic. The locomotive was further tested.
[edit] Reason for abadoning the serial production
Serial production never happened. Although Zagreb Workshop showed, that it could do the job, the real full reelectrification of Zagreb-Rijeka line has not happened yet. Hrvatske Željeznice do today rent multisystem locomotives in order to drive the whole line non-stop. A power conversion on the total line is slated to be finished soon.
[edit] Liveries
These two locomotives had different liveries. One had the red livery, reassembling the original "ASEA" coloring, and the other one had grey livery with blue stripes. The grey with blue livery was later chosen as HŽ standard company livery.
[edit] Possibilities in the future
The 1061 and subsequently 1161 have reached almost the end of their useful life. Probably, newer and more modern locomotives will be purchased to serve Zagreb-Rijeka line. Either the expirience from this two prototypes will be used to modernise series 1061 to 1161, once Zagreb-Rijeka line gets consistent voltage, or this units just were a successful, but failed experiment.
