@mae i was travelling in bmz73 apparently in that nightjet and like it kinda looked old I guess though like also the only UIC-Z coaches in Poland are used usually in Express and EuroCity trains so it's not that you see them often
@mae like, we have so many Y standard coaches that they just end up modernising the interior from 8 seat to either 6 seat or 2+2 open saloon, unfortunately without changing the bogies, but like, eh
@jeder@mar the D is for Durchgangszug, aka "through train", it's very old nomenclature for high-speed trains. The only D connections in Austria nowadays are filler trains to increase capacity during peak hours on long-distance relations to and from Vienna
