@lina let's compare capacity and size. A Konstal 105Na wagon was rated for 20 seats and 105 standing places, it was 13.5m long and 2.4m wide, usually ran in configuration of two coupled wagons (non-articulated so they were separate units) so you could double that for easier comparison. A Pesa Swing is 30.12m long and 2.35m wide, with articulated body. Its total capacity is 40 seats and only 161 standing places. Subtract a few of those seats too as it has foldable jumpseats in the cripple/kiddy stroller areas and it's kind of pathetic. You can't comfortably stand next to the angled seats either since people tend to be assholes and not bother compressing their legs.
