I confused Kunowice
Kunowice (near the Oder) was also well known for being the site of the railway border control between Poland and Germany before Schengen.
I had an amusing experience there a few years ago. The old train station was up for sale, and I got to meet one foreign investor who was looking for a place to act as a Polish base for his German company. I was going to Frankfurt (Oder) anyway, so I offered to have a look at some properties in the borderland there - he offered to cover my petrol/motorway costs in exchange, so it was a win-win for both of us.
Anyway, I turned up at Kunowice train station quite late at night, and some security guard was there. I explained the situation and asked to have a look inside, and if he would turn on the lights so I could take some photos. He got quite angry and upset, so I asked him what the matter was. It turned out that he was working nights in the station, but that it was closed permanently and that there was no power supply. From what I understood, PKP were saving money by not heating the place and not providing power, and so he was stuck inside this cold and dark building all night.
I gave him some money in exchange for getting to look inside, and to his credit, he showed me everything there was to see about the building. He saw the funny side after a while, and he explained that he had constant trouble with vandals coming to try and break windows/etc late at night.
