That's a refurbished one, although there are various levels of refurbishment,
The better ones have had an external and full internal refurbishment complete with new panels replacing the old wooden style ones, new lights, LED information displays inside and out, new seats, removed internal doors instead of those tiny sections, a full relivery and new external light clusters and front design and new windows and some even have Wifi!
This is the highest spec ones, recently refurbished, called the EN57ALC, operating for various parts of PolRegio.
However the following are more common:
- The medium refurbished ones that have had new seats, new lights, a relivery and a cheap full PIS.
- The lightly refurbished ones with new seats, new external lights and and an external PIS.
- The barely touched ones that had their old seats re-covered and a small LED display on the front.
If you fancy sampling many different micro fleets of them, go to the tricity area and take a few SKM trains between Gdansk-Gdynia-Sopot - when I was there last there was about 6 different standards of refurbishment of the EN57/EN71, from the good, the bad to the ugly and the downright wrecks that should have been turned to razor blades long ago.
These are the two most common interiors, prior to any kind of refurbishment
If you want more variety still, take a couple of PolRegio trains between the train stations and you'll see even more different versions which have a lot of 'character' as someone wisely put it.
