It seems that CZ LOKO's 753.6 demonstrator locomotive 753 604-8 has been sold to SD - Kolejová doprava. It is now carrying the SD-KD colours and is already in service for the Czech railfreight operator. We are still looking for confirmation on this.

The image (by Pedro Almeida) shows the locomotive with 741 701-7, carrying a livery resembling the colour scheme of Italian operator Dinazzano Po (DP).
