ČSD Class ES 499.1 is a class of electric locomotives used primarily for passenger trains in Czech Republic and Slovakia. Now classified as Class 363, these locomotives passed to České dráhy, rail operator in the Czech Republic, and to ZSSK, rail operator in Slovakia. Class 363 is also used by ČD Cargo and ZSSK Cargo for hauling freight trains.[1]

ES 499.1 locomotives operate both on the 3,000 V DC system and the 25 kV 50 Hz AC system.

History

In 1980 Škoda produced ES 499.1001 and 1002 as prototype locomotives for the replacement of the existing ČSD fleet. Production series locomotives started to be delivered in 1984. Two single system derivatives were also created S 499.2 (AC) and E 499.3 (DC). During 1990 further development to run at 140 km/h lead to the ČD Class 362, but an order for 30 locos was canceled due to financial problems. Some ČD Class 363 and ŽSR Class 363 locomotives are being rebuilt as 362s. Since 2011, they have also been operated with control trailers.

Power regulation

In 1980, these locomotives were the world's first multi-system locomotives with power thyristor pulse regulation. This regulation has minimal losses compared to older resistive regulation with much higher losses. This gave the locomotive its characteristic sound in three frequencies (the first is 33,3 Hz, the second is 100 Hz and the third is 300 Hz) when the locomotive is accelerating.

Usage

363s are currently used to haul these services

Disposition[2]

As of June 23, 2008, 12 363s remained in service with ZSSK,[3] 23 with ZSSK Cargo,[4] 63 with ČD[5] and 47 with ČD Cargo.[6]
