> Additionally from Amsterdam to Zürich 3 people got robbed while still in the Netherlands. This train is reservation only, they could at least lock the doors or something to prevent criminals from boarding.
compartments can be locked, locking up the entire train and having the entire boarding process be bottlenecked on ticket inspectors seems highly impractical
On exactly 1 platform out of 15 though, and it took several years to rework all the access routes to and from that platform. It is also already much too small for all the extra capacity it will need when Eurostar intends to start using longer trains.
ideally yes but i don't think it can be done with the current organizational structure of the european rail network. not consistently, only bilaterally
There is already a bottleneck on these trains because the staff need to bring you to the compartments. Unlike regular trains there is a lot of staff (one per carriage).
Boarding in Zürich you can only enter in one door for the sleeper.
Also most stations are exit only and no new passengers can board.

No, that's just not how it works most of the time with ÖBB, not even in Nightjet. I walk in and the ticket inspection happens later. Yes there's staff outside with NJ to sort you in, but you can walk around them. At no point are they a real bottleneck.
