Although the classes 499.0 and 499.1 were also used in front of freight trains, the tractive effort in this area of application was limited. When the E 499.157 was damaged in an accident, the opportunity was taken to provide it with a different gear ratio for a top speed of 90 km/h as part of the repairs. Due to the limited adhesion, the starting tractive effort did not increase, but bigger pulling power was available at the usual speeds for freight trains. Although this locomotive was dismantled after testing, 85 examples of the new freight version were built in 1960 as the class E 469.1. These locomotives also had electric train heating and could therefore also pull passenger trains, but this only happened rarely due to the lower maximum speed.

When there was a further need for freight locomotives for 3.000 volts direct current, another series of 55 units was built in 1967 as the E 469.2. These had a revised locomotive body and driver's cabs based on the class E 669.1 and were the first Czechoslovak DC electric locomotive to have multiple controls. When some steam locomotives still had to be replaced a few years later, another 29 units were built in 1971 as the E 469.3. The three series later became the classes 121, 122 and 123. Since after the division of Czechoslovakia no major railway lines in Slovakia were electrified with direct current, they all came to CD. According to their age, the 469.1 were the first to be either retired or sold to private railways by 2006. Most examples of the newer series were retired between 2010 and 2020.
