1142

Locomotive 1142, used for hauling passenger and freight trains on mountain and lowland lines, is the first locomotive developed and produced in Croatia. Constructionally, it is based on locomotive 1141 (JŽ 441), even though in many ways it can be considered a brand new type: most importantly, this locomotive is more powerful and equipped with thyristor motor control and a more modern case design. In the early 80, the former ŽTP Zagreb was looking for a new locomotive, better than locomotives from the series 441, subseries 7, which were the best locomotives at the time. The factory Končar, in cooperation with the factory Janko Gredelj, made the first prototype and delivered it to ŽTP Zagreb on 4th October 1981. After a several years long testing, 15 locomotives 442 were ordered from Končar. Locomotive HŽ 1142 (JŽ 442) is equipped with an electro-dynamic brake (2400kW), a device for bandage oiling, an auto stop device, a radio device, and a multiple operation function. In the late 80s, ŽTO Sarajevo (presently Bosnian and Herzegovinian Railways or the BIH Railways) showed a considerable interest in locomotive 442. It was supposed to buy 5 items, but the deal never came through on the account of the war. The JŽ (ŽTO Belgrade, at the time) also showed a general interest, but it has never bought any locomotives because the speed limit on that part of the network was only 140 km/h. There were also certain indications that some railway companies outside Europe might buy locomotive 442 (Iran and China, for example). One of the 16 locomotives 1142 was destroyed during the war, in 1991 in Vinkovci. The other 3 were operated by the Hungarian Railways (MAV) in the late 90s. Today all 1142 locomotives are on the HŽ network.

The 1142 class locomotives can be observed on Zagreb — Vinkovci line hauling IC trains or heavy freight trains, and occasionally on Zagreb — Dobova (Slovenia) line, as well as Zagreb — Koprivnica line (but very oddly). The units still have the original red-orange livery with white stripes. The three units which were borrowed to MÁV (Hungary) have a tiny little distinctive spot: the HŽ sign on the front sides is white with black line inside.
