I arrived in Prague this morning, 15 minutes late (we arrived in Berlin before schedule, and arrived in Czechia on time, the delay originated in Czechia this time).
The train arrived in Roosendaal 13 carriages strong. 10 couchettes, two sleepers and one seating car. Only odd thing was the two sleepers were AB33's, not the former type p ones that normally run. I suspect problems with the stainless steel carriages was the problem earlier this week, they did not run. This shows having an extra rolling stock partner, because of the second route, helps in having some extra flexibility. The situation is precarious though, two AB33's on both European Sleeper routes, plus one on RDC's aitoreise zug means that all 5 AB33's are now on the route, so no spares left.
For the journey itself. I had a private comfort standard compartment. I liked the setup in which you always have a bench to sit one while having a bed available. The extra mattress was comfortable (perhaps still a bit on the hard side, but I prefer that). Everything was clean, the toilet worked and was neat throughout the journey. The route has some scenic parts, extra enjoyable with opening windows. Despite the challenges they have and the problems that exist I am very happy the service exists.
