The two units of JŽ 462 (HŽ 1161) series were derived from the JŽ 362 (HŽ 1061) series. The purpose of the project was to meet the needs for freight haul on mountain tracks electrified at 25 kV ~ 50 Hz, at relatively low costs. The very special motive for such a proposition was the re-electrification of Zagreb - Rijeka line from 3 kV DC to 25 kV ~ 50 Hz, which was currently in progress. The old 362 series had to be made use of, otherwise it should had been cashed. The main aim of the project was to preserve as many existing parts as possible, and if some should be replaced, the substitutes had to be equal to those of the 441 series. The modified locomotive should also comply with contemporary technical regulations. From the existing parts of the 362 series, the bogies were retained, the main frame was reinforced, the traction motors and the pantographs were modified. The parts equaled to the 441 series are: the main transformer with the current switch, direction switch, contactors, electrical amplifiers, air compressor and some parts of the pneumatic devices. The result of the reconstruction was the first six-axle diode locomotive at HŽ, carrying the 1161 serial number.

The first unit chosen for the overhaul was the damaged 362-106, which came to Zagreb Workshop on 1980/06/25. After the overhaul, it became the serial number 462-001. The second to be reconstructed was also damaged, no. 362-003, which had been waiting at the workshop yet since 1979/07/28. Once the transformation of the 462-001 was completed, by the beginning of 1988 started the functional testing. On the 23rd of March the first test drive was carried out at Locomotive Overhaul Department, and subsequently the unit was permitted into the traffic. The locomotive was tested afterwards too, on different rail sections and under different conditions, according to the prototype testing program.
