In the 1970s the new giant
Katowice Steelworks, then in its most prosperous period, required great quantities of iron ore. The main source was mines near
Kryvyi Rih (then in the USSR, now in Ukraine), from where it was transported by rail via
Medyka,
Przemyśl, and
Tarnów to
Jaworzno Szczakowa. This line had inadequate capacity to carry the traffic. The
Polish State Railways PKP considered two options: to expand existing transshipment facilities at the border (the
break of gauge point) and to upgrade existing railway line to three or even four tracks to allow more freight to be carried, or to build a new broad-gauge line to ease transit across the border. The latter was chosen, the advantages cited were that the newly-designed line could be built to accommodate the heaviest trains allowed to run on broad gauge network, there would be no need for an unfreezing facility at the border (in winters ore arrived frozen solid, presenting a challenge at the transshipment facility) and PKP needed not to use its own wagons to transport the goods on the Polish network as the Soviet wagons would be used for the entire transport. A broad gauge line with direct connection to the Soviet railway network also was of
strategic importance, allowing Soviet troops to be quickly deployed closer to the
Iron Curtain. The new line was designed by CBSiPBK (
Central Bureau for Railway Construction Designs and Studies) in Warsaw, Józef Skorupski was the general designer, Twenty-one other design bureaus, eight geological companies and three technical universities took part in the project. The line was built partly alongside existing standard-gauge lines which facilitated the construction works. To save costs, the line was routed through
Roztocze National Park despite intensive lobbying by the park management. The line opened in 1979 and was used to import iron ore from the USSR and export coal and sulphur. After the fall of communism and the economic changes of 1989, traffic greatly diminished. In 1994 export of sulphur stopped. Various schemes are being tried to increase its profitability, such as offering transport and forwarding services to all interested customers, leasing of commercial space and some rolling stock maintenance. In the 1990s the LHS line was used by long-distance passenger trains to Russia and Ukraine. Initially, it was one pair of fast trains from
Moscow to , running every other day. In 1993, two pairs of trains
Lviv – and Moscow – Zamość North were added. In 1994, passenger trains on the LHS line ran only once a week on the route
Kharkiv – Olkusz. Since the mid-90s, passenger trains have run sporadically as special trains. In 2001 a new company within the PKP group, PKP Linia Hutnicza Szerokotorowa, was established to manage the line. On 5 January 2020 the first intermodal container train from
China used the line to reach the Sławków terminal, after traveling the route from
Xi'an via Kazakhstan, Russia and Ukraine over 12 days. The company operating the line hopes that regular connections with China are established, taking advantage of the fact that its wide-gauge permits quick crossing of the border between Poland and Ukraine. The company is in the process of installing
warning lights (and, in some cases, barriers) at level crossings, extending the Hrubieszów LHS station and upgrading the train control systems. The works are due to be completed by the end of 2025. Since 28 February 2022, special passenger trains carrying refugees from Ukraine, during their highest influx following the
Russian invasion on their country, were run on the line to Olkusz, where a
tent town has been established to accommodate them before they continue travel by standard gauge rail or by road. ==Names==
