ČSD Class E 499.3 electric locomotives were used primarily for passenger trains in Czechoslovakia.

Because it was a slightly modified version of ČSD Class ES 499.1, there weren't any prototypes built.

All 30 locomotives owned by ČD Cargo were rebuilt to class 363.5 (dual voltage) by Škoda.

Because of the financial problems of ČSD (and then ČD and ŽSR) after the Velvet revolution, Škoda rebuilt 9 pieces of the fourth series and sold them to FNM, Italy.

[3] In 2010, all E630 locomotives were sold to Czech private operator RegioJet and were rebuilt to class 162.
