@ielenia they are standard on anything that is 10 meters and longer, hell, in czechia they put 4 doors on 12m, while we put them on 18m in bigger cities
@jeder heres a 40' and a 60', you can see that they only have 2 and 3 doors, respectively (if you look really carefully lol, the picture doesn't show it the best)
@ielenia our 18m get 3 doors but yeah, bigger cities get versions with 4 doors, sometimes 5 (though these are usually longer than 18m, usually like 18.75-21m)
@ielenia@gen iirc my city was like one of the first in poland to phase out high and mid floor buses because we got quite a bit of used MAN NL2x2s and of course they were like low entry but also not exactly because iirc the only step was at third doors?
