Between 1952 and 1958 renowned Škoda works of Plzeň supplied 100 class E499.0 four-axle universal electric locomotives to Czechoslovak state railways ČSD (factory type 12E). They were built under license from Schweizerische Lokomotiv- und Maschinenfabrik of Winterthur and Société Anonyme des Ateliers de Sécheron of Genéve. Two more were supplied to the USSR (class ChS1, or ЧС1 in Russian script – factory type 24E1) and ten to Northern Korea (factory type 22E1). With the ČSD these locomotives were later re-classed 140; they were commonly nicknamed ‘Bobina’, after the Bo’Bo’ axle arrangement.

In 1957 a modified version was developed that featured indigenous Škoda-Chadži transmission that replaced the original Sécheron type. Prototype (factory type 20E1, s/n 3393/1957) was followed by sixty production examples, delivered between 1959 and 1960 in two batches, each numbering thirty examples (factory types 30E1 and 30E2, differing only in minor details). Compared to the original ‘Bobina’, they were slightly longer and could be easily distinguished by rectangular side windows instead of the round ones. These locomotives initially hauled mainly express trains; after the introduction of class 150 in 1978 were gradually relegated to less prestigious duties. Two examples (141.004 and 141.012) were still in use with Czech state railways ČD in mid-2016. Class E499.1 served as the basis for factory type 44E1, of which thirty examples were built in 1961 for Poland (PKP class EU05).

In March 2009 five locomotives of this type (141.014, 019, 029, 036 and 045), withdrawn between 2003 and 2005, were transferred to the ZNTK Oleśnica repair works in Poland. Two of them, 141.014 (Škoda 3831/1958) and 141.045 (Škoda 3862/1959) returned to Czech Republic in September 2010, this time to DPOV Přerov repair works. After overhaul they were restored in service and delivered to Wrocław-based STK company in October 2012. They were re-numbered 30E1-014 and 30E1-045, respectively; the latter designation is somehow inconsistent, as this locomotive in fact belongs to the 30E2 sub-type. Currently (late 2018) both are still in use. The remaining three examples were sold for scrap in November 2013.
