It's here - the #PKPIC HSR EMU tender is now open. 20 trains + option for up to 35 more, 320 km/h minimum, minimum approvals PL DE CZ AT (BE NL FR CH IT SK HU welcome), 402 seats, must have a restaurant section, a zone for children and *8+ horizontal bicycle spaces*. Also required is a secondary satellite backhaul for on-board Wi-Fi. In safety and comm systems, ETCS L1+L2 with ability to upgrade from GSM-R to FRMCS in the future and also classic analog Polish stuff. (Running these beyond Berlin and Leipzig appears to be a distant stretch goal at best, so they might not necessarily bother with LZB if it isn't required for everything high-speed-capable)
They say the plan is to start with the Y high-speed line that will be built in parallel running trains Warsaw-Wrocław and Warsaw-Poznań-Szczecin/Berlin (alternating), expanding to Tricity, Leipzig and Prague routes if they use the full option as the HSR buildout allows (yeah, those latter plans are kinda crayon level right now): https://www.rynek-kolejowy.pl/wiadomosci/pkp-intercity-gdzie-pojada-pociagi-kdp-mapy-126149.html
