Though those aren't standard gauge, are they?
If Albania wanted DMUs anything fairly old (so they can be maintained by traditional mechanics) from mainland Europe would do well enough. Nothing really from the UK as it's a low-platform country so you want units with stepped entrances.
I do wonder if it'll eventually see something like Cambodia - a foreign business coming in to take it over and do it up properly with modern kit (even though that did end up back in Cambodian hands once done).
I think it may well be the best chance of train travel making any kind of comeback in Albania. I can only compare it to what I saw in Myanmar, at least around Yangon, old JR carriages were running, although they had been left to decay as many of the seats were in a poor state and some of the doors didn't close properly. Still better than mainline Burmese rail services, but not a shadow of their former self when the same trains were in Tokyo, which the old route maps seemed to suggest they had been.
If Albania was to receive any kind of international investment in its railways, I'm guessing there would be a push to link the country to those around it to create a kind of Balkans network and another stable rail link between south and north Europe.
