@erin this is ZNTK PoznaΕ's SA105 (213M*), not Pesa EN81 though β:woozy_baa:β however PESA SA103/SA106/SA135 (214M*) and EN81 (308B) which would be equivalent are quite a bit longer than this, they are as long as one normal/intercity carriage, so 214M is 24m long, and 308B is 26m long, while this is just 17 meters long, and since I've ridden both 213Ma and 214Mb, 213M is considerably worse in comfort because of how short it is, and because it doesn't use conventional bogies
@erin either way, you weren't really off with the production numbers, they made like 7 of them at most, although their two-car long series was bit longer, though also just 10 units were made
