Seems like a decent unit to me. What exactly was wrong with it?
Meanwhile, the station looks to fit the defenition of the word 'dump'.
That will be a Regio/InterRegio, there are lots of them floating around, that one has had a refurbishment, since the ones that have not don't have the LED. There are various levels of internal refurbishment on those units, from the very modern interior but cheap looking, to the lightly refreshed depending on how much money PR had at the time.
The history behind those trains is very interesting, in that whilst now they are operated, along with all other Regio services by Przewozy Regionalne, there is a complex history behind that organisation and the fact they are very old trains operating on mostly local services serving a lot of run down stations is not really a fault of the company itself.
Przewozy Regionalne used to be part of PKP. But because of EU rulings PKP had to be broken up. In early December 2008, PR was forced to transfer virtually all of it's most attractive routes, paths and best condition stock to it's PKP parent. After which the ownership of PR was transferred to 18 regional authorities and the former PR routes that went to PKP were re branded TLK.
Ever since PR have been crippled by high track access charges, an aging stock and a huge debt and various issues with access to stations which has got worse and worse, particularly over the last couple of years. It's safe to say that life hasn't been made easy for them and despite that, they still have achieved many things despite the odds being stacked against them.
They introduced the Balice Ekspress train from Krakow Airport to Krakow many years ago, which people said couldn't be done, they were years ahead of PKP on offering online ticket sales, introduced ticket vending machines for the first time to Poland and played a big part in contributing to station improvements around Euro 2012 and their RegioEkspress offering that they aimed to expand going up against PKP Intercity was way ahead of PKPs of the day.
However they were never really going to be able to properly survive in the market that they were in and soon will most likely vanish completely with RE now dead, IR basically dead assets and investments they made now bearing the PKP name and most regions now looking to bring their operations fully in house I can't see them surviving for long. The shame is generally their RE/IR services were far more punctual than PKPs and the staff were much more easygoing as well.
