Since 1995, some EU07 locomotives have undergone a reconstruction, in which new traction motors with a higher permissible operating temperature - LKb535 were installed and the gear-ratio was changed from 79:18 to 76:21.
The change of gear ratio did not, however, increase the design speed (misaligned transmission system - hollow shaft bearing on slide bearings), but decreased the engine speed, making it difficult to drive freight trains with this locomotive.
In addition, they received new livery, control sockets were dismantled, driver's cabs received thermal and acoustic insulation and new driver's and assistant's seats, and electric wipers and halogen headlights were installed.
In the years 2012-2013 5 EU07 of Przewozy Regionalne was rebuilt to EP07P type, they received a new numbering from 2001 onwards.
The modernization included installation of static converter, WN and NN cabinets, new panels in driver's cabins, air conditioning and repair of traction motors.
