~Sound BR S499 CSD IV + PluX22 Dec.

In the 1960s, the CSD began a comprehensive electrification of its railway lines in the southern part of the country with alternating current. For this purpose, Škoda procured several lots of powerful locomotives for express train service, which are probably among the most striking electric locomotives in Europe due to their unusual appearance with large, rounded panoramic windows at the front. Since the locomotive body sitting on the welded steel frame was covered with plates of fibreglass-reinforced plastic, the locomotive soon received the nickname "Laminátka". A total of 145 S499s of the S499.0 and S499.1 were delivered to ČSD from 1968 onwards. Of these, 25 locomotives were classified as class S499.1, the only difference to the S499.0 being the higher maximum speed of 140 km/h. However, from 1978 onwards these 25 machines were all rebuilt to the S499.0 series. After 1992 the majority of the universal locomotives remained with the 'SR. The machines of ČD are mainly used in freight traffic.
