@Suiseiseki HDMI is deeply unethical as it is not an open standard, is patent-encumbered and can be a vessel to anti-freedom restrictions. Anything else is irrelevant.
@lina admittedly, the angled seats serve a purpose in that they're located on top of the wheels. Konstal trams had an elevated deck but Pesas are low-floor so they had to sacrifice some of that space. It's still bad though.
@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.
@lina i like them too. Pesas, which are gradually replacing Konstals, may be more comfortable but the way they're arranged inside is bothering me. Compare the straight and sensibly, symmetrically placed seats made from easily washable hard material (perfect for washing away pee of some drunk bum who sat in it) vs. the illogically angled seats in a Pesa Swing.
@lina FYI Konstals are using more or less the same tech as Americans' PCC, which is super old; pre-war there were plans to loicence it from them but post-war the design was reverse engineered and directly copied from inspired by units graciously handed over by the Czechoslovaks with liberal use of political pressure and threats, who held an actual loicence. They were modernised a few times but fundamentally they're still the same.
@lina wouldn't work on trams over here either. Maybe with some Pesas but Konstal trams are no go since they accelerate and brake abruptly. Pic related, Konstal 105Na in Kraków's livery, pic by Igor123121 under CC BY-SA 4.0 loicence.
