It looks like US, but look closely ...

And a sign that Alco's never die or at least they give a good fight

Portugal and Greece are the main surviving Alco/MLW outposts in Europe.

Although it's an american engine (a good 'ol one), and the paint scheme looks like CP (it was studied in Canada), it's not the CP that you're thinking it is

The date on that image says it was taken in 1996.
That's over 15 years ago - are the ALCO's still operating in Portugal?

Duno about Greece, but here in Portugal only 5 Alcos (they're Bombardier's, but basically their inhards are pure Alco, belonging to the MX 627S export model type), are active (I think there are some DL535s still working in the Ponferrada - Villablino Railroad in the North of spain, converted to metre gauge). The rest are wether stored (MLW's model MX620, 20 units) or working in a 'new life type mode' for track contractors (5 veteran RSCs just like the one in the photos). Here are some more infos about all these models

From the original group of 17 RSC2 & 3, 5 are operational, but now are being used by track contractors and supporting some nice paint schemes, here are some more recent images (off course these units now tend to work on the 'night shift')
