HŽ series 1061
Encyclopedia
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 Slovenian version has the original yellow livery and is used throughout the country.
The locomotives are split in two series:
and was originally donated by the Italian
government. The uniqueness in contrast to other Croatian electric locomotives is that it uses the 3 kV DC system
, and is only deployed on the Šapjane-Rijeka
-Moravice
Line. The rest of the overhead catenary in Croatia is 25 kV
. The part from Zagreb to Moravice was re-electrified to the standard voltage. The remaining part, on which this locomotive is still deployed is slated to be converted, too.
, and in some parts from FS Class E646
.
Like E636, JŽ 362 has six motors, each providing 440 kW (1st series) and 472,5 kW (2nd series), and rheostatic regulation; the tractive effort is also higher (360 kN on start, 283 kN continuous).
On 1st series two La TA 241 Westinghouse compressors provide air for pneumatic systems; the 42 V batteries are recharged by a 2.83 kW dynamo, which provides a current of 68 A, activated by the rheostat and motors 1.1 kW fans, model "Marelli/Koncar".
On 2nd series compressors and battery recharge systems are identical, but fans are 3 kW "Aeroto" type and are activated by alternators, providing a 380 V AC three-phase voltage.
Also, rheostatic type braking is possible, on a similar way used on experimental unit E636.082.

History
A locomotive was needed which could operate on a mountain railway line with very hilly terrain. The steam and diesel locomotives at that time could not fulfill the request, as they could not generate sufficient power. Therefore, the line was electrified, at the then common voltage of 3kV DC. These locomotives were deployed on this line between 1960 and 1964 and (numbers 001 to 019) and between 1968 and 1969 (numbers 101 to 110).The locomotives are split in two series:
- JŽ 362.001-040 (First Series) : 40 locomotives built between 1960 and 1967, 35 within 1964, then only 5 in the following 2 years due to indecisions about modifies to adopt on seconds series.
- JŽ 362.101-110 (Second Series): 10 locomotives built in 1968.
Uniqueness

The FS E636 is a class of Italian articulated electric locomotives. They were introduced in the course of the 1940s until the 1960s, and have been decommissioned in 2006. They have been one of the most numerous Italian locomotive group, and have been widely employed during their long career,...

Future plans
When the whole line is re-electrified and since the useful life of this series is nearing the end, it will probably soon be scrapped or all units will be eventually converted to series 1161HŽ series 1161
The HŽ Series 1161 is an experimental electric locomotive series belonging to Hrvatske željeznice.- Prototype :The two units of JŽ 462 series were converted from the JŽ 362 series. The reelectrification of the Zagreb - Rijeka line was planned, involving change from 3 kV DC to . To keep costs...
