Wow, is this a rare guest in these parts?

It was a relatively rare machine to catch, it was borrowed by a private carrier from ZSSKC. Sadly because of the new ETCS signalling system and also due to Žilina station being switched from 3 kV DC to 25 kV AC, Slovak DC machines such as the 183 class will not be able to visit CZ from the 1st of January 2025 anymore.

Oh, that's a shame. And what will be the habitat of the 183 then?

For the few that still remain, from the freight station Žilina-Teplička (the transition from DC to AC will happen somewhere between this substation of Žilina, and Žilina proper) eastwards.
If I had to guess they will be, or already are, transferred from the Žilina depot to Čierna nad Tisou depot. They only have a single regular freight train left, that being the short border service from Čierna nad Tisou to Chop, Ukraine. I believe they have some sort of a Škoda subsidiary factory there which requires parts made in Mladá Boleslav, which is what the 183 tows there.
Other than that they infrequently show up on random freight trains from Čierna nad Tisou, when there isnt a class 131 locomotive available I assume. That being said there is really just a few left. Other than this one, numbers 001, 004, 011 and 043 are all thats left. Of course those are the ones owned by ZSSKC, you have potentially still dozens left, if you count the many 181/182/183 machines owned by mainly Polish, but also some Czech and Slovak companies.
Much more endangered than these are the 181/182 locos owned by the our ČD Cargo, which will either be sold or probably scrapped, because of the ETCS issue.
