Die erkennt man ja kaum wieder. Könnte glatt ein Neubauzug sein. Hat sich beim Antrieb etwas verändert?

I can describe changes only in English...sorry!
EN57-2000 is only modernized during major repair EN57.
New front (now there is only one windscreen - see my pictures), new internal doors, seats, cockpit and toilets.
Instalations moved under the roof (from top or the train)
New screw compressor instead of piston compressor.
New converter.
New springs.
New painting (RAL9005, RAL7026, RAL9006, RAL3003).
And I think - that" s (unfortunately) all....
I hope you can understand this.
