no wonder PKP Intercity decided to say fuck it with all of the new stock numbering because like, let's decipher all that shit with www.transportszynowy.pl/Kolej/oznaczeniapoj
EU160 - 1st gen 3kV DC Newag Griffin, this could possibly be EU12, i suppose, since it is universal 3kV with 4 axles and iirc 01-14 isn't filled up, there's no Ex10, nor Ex12-14, there was EU11 however, Adtranz 113E, which was supposed to be the late 1990s-early 2000s successor of EU09 however PKP didn't have funds for it, so all them ended up in Italy, 15-19 are reserved for 4-axle locomotives powered by AC current only, which, like, cuh
EU200 - 2nd gen 3kV DC/15kV 15.6Hz/25kV 50Hz Griffin, PKP Cargo assigned to its 2nd gen 3kV DC/25kV 50Hz 2nd gen Newag Dragon something like ET43 which is in the bracket 40-49 which according to the scheme is for "everything else that is an electric locomotive", AND there also was an ill-fated EU43 which was an Adtranz 112E that was able to be powered from 1.5kV DC/3kV DC and 15kV 15.6Hz but it shared the same fate as EU11
anyway, this would probably be something like i don't even know, EP47?? P or U, pretty much vibes based at this point, but given it has some, ekhm, difficulties reaching Zakopane, i'd say P is a better fit. EU44 is Eurosprinter ES64U4, while EU45 is ES64F4, and EU46 is Bombardier Traxx of Koleje Mazowieckie i believe, which makes me believe is the reason why Pesa Gama does not have this number assigned in the first place and instead uses its type number 111E, because there's no space for this do you see the flaw already (Newag locomotives are peculiar because their type number is not something like 123E but E4DCU in case of 1st gen Griffin/EU160, E4MSUa in case of EU200, E6ACT in case of 1st gen Dragon [no i don't know why they went with AC moniker here even though the locomotives cannot do AC], and E6ACTab*whatever* in case of 2nd gen Dragons, outside of ET43 which i believe are E6MST or something like that)
ED250 - now the fun stuff begins, Alstom ETR600/New Pendolino, 4-system iirc 7-carriage long high-speed EMU, suffice to say, all the numbers for "other" EMU types are long depleted, which would make this something like ED101, because that's the lowest available number not anticipated in the standard, and EN100 is already used by Newag 39WE of WKD
ED160 - Stadler Flirt, 3kV DC 8-carriage long EMU for long-distance, same as above, ED102 most likely? however it might be something way different because of how many EMU types were being made at the time
ED161 - Pesa Dart, 3kV DC 8-carriage long EMU for long-distance, same as above, ED103? but as above, it might as well have been something like ED105
so, while it would be nice to have a single scheme for all the trains in Poland, it would need not just an overhaul but a whole start from scratch
