Hello, Balkanexpress!!
Hello, Oloï!
Some comments to your shooting in St Charles station:
After the blue buffers, the grey electric engine wears the "ghost livery".
As en explanation, you see the next pic, where are on the same grey livery, drawing decals, that 's the "en voyage livery".
The SNCF had heavily paid a design office for these drawings. And paid this office again at each usage of this drawing.
The Direction of the SNCF had changed, and decided to denounce this contract. And paid again for this.
For a time, engines are simply painted in grey, without drawings. That's the "ghost livery".
Assizes said THESE drawing are artistic property of the design office.
So designers of SNCF made a new drawing, similar but non identical, which is the SNCF property, and applied on engines.
But you have to know, the director of this design office was a friend of the french republic president... ôô
Cheers... JMfret
