Class E 499.1 electric locomotives were constructed and built by Škoda Works in Plzeň for use in Czechoslovakia by the ČSD. They were also used outside Czechoslovakia in Poland as class EP05 and in the Soviet Union as ЧС3 (ChS3).

After the fall of the iron curtain and consequent upheavals in railway operations they remain in use with a number of railways. Still in the 1980s ČSD locomotives were renumbered to the class 141. After dividing Czechoslovakia in 1993 all locos of this class have remained in Czech republic.

The locomotive was produced in the years 1957-1960 in three types. 20E1, the prototype, different from serial production, 30E1 and 30E2. 61 engines were built in those series.

The prototype (E499.101) came into service on February 29, 1959. Most of locomotives stationed in Prague, but some of them were sent to Ústí nad Labem and Česká Třebová. Currently the whole series is being systematically withdrawn with last units used in Prague, Olomouc and Ústí nad Labem.

Class E499.1 electric locomotives are used to pull both passenger and freight trains. They have driving cabs on either end of the box. This engine was not suited for multiple steering and shunting purposes. On a straight, horizontal track it could pull 600 t. passenger trains with the speed of up to 120 km/h and 1000 t. freight trains with the speed of 80 km/h.

In need of modern electric locomotives for passenger trains, and unable to get timely delivery of EU06 locomotives from England, Poland bought 30 locomotives type 44E from its southern neighbours. In 1961 it was the most modern locomotive running on Polish rail tracks. EU05 locomotives pulled fast passenger trains and were based in Warszawa Odolany and later in Warszawa Olszynka Grochowska depots. Those locomotives serviced chiefly connections from Warsaw to Poznań and Katowice.
