It is the first six-axle locomotive at Hrvatske Željeznice. The 1061 number was changed to 1161, in order to indicate a new subseries.

Prototype
The two units of JŽ 462 (HŽ 1161) series were converted from the JŽ 362 (HŽ 1061)HŽ series 1061
The HŽ series 1061 is a 6-axle articulated electric locomotive series still used by Hrvatske Željeznice. It is similar to, and developed from, the Italian FS E636. It was known as JŽ series 362 in SFRJ and currently as SŽ series 362 in Slovenia...

The bogie
Bogie
A bogie is a wheeled wagon or trolley. In mechanics terms, a bogie is a chassis or framework carrying wheels, attached to a vehicle. It can be fixed in place, as on a cargo truck, mounted on a swivel, as on a railway carriage/car or locomotive, or sprung as in the suspension of a caterpillar...

Pantograph (rail)
A pantograph for rail lines is a hinged electric-rod device that collects electric current from overhead lines for electric trains or trams. The pantograph typically connects to a one-wire line, with the track acting as the ground wire...
had to be modified for the higher voltage.
Newly used parts included: the main transformer
Transformer
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors—the transformer's coils. A varying current in the first or primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic field...

Amplifier
Generally, an amplifier or simply amp, is a device for increasing the power of a signal.In popular use, the term usually describes an electronic amplifier, in which the input "signal" is usually a voltage or a current. In audio applications, amplifiers drive the loudspeakers used in PA systems to...

Air compressor
An air compressor is a device that converts power into kinetic energy by compressing and pressurizing air, which, on command, can be released in quick bursts...
and some parts of the pneumatic devices.
It is the first six-axle locomotive at Hrvatske Željeznice. The 1061 number was changed to 1161, in order to indicate a new subseries.
History
- First unit: arrival at Zagreb Workshop on 1980/06/25.
- Second unit: had been waiting at the workshop since 1979/07/28.
Testing program
On 23 March first test drive was performed. The unit was permitted into the traffic. The locomotive was further tested.Reason for abandoning the serial production
Serial production never happened. Although Zagreb Workshop showed, that it could do the job, the real full re-electrification of Zagreb-Rijeka line has not happened yet. Hrvatske Željeznice do today rent multi-system locomotives in order to drive the whole line non-stop. A power conversion on the total line is slated to be finished soon.Liveries
These two locomotives had different liveries. One had the red livery, reassembling the original "ASEA"HŽ series 1141
