Railways of Germany forum might be the best to ask.
The Z type also had dividers like that.
Thanks for that, I will follow up through Railways of Germany.
I recall a trip in a YF from Madrid to Heulva in 1985 which has to be the most uncomfortable journey I ever made in a sleeping car. Originally the YFs for Spain offered only one or two berths per compartment, but some later ones had two compartments at the end of the car with three berths and I was in one of these, my berth on top of the bogie, a bottom berth which seemed to be almost touching the wheels! Whether due to the condition of the suspension or of the track or a combination of both I will never know, but I felt every set of points that night - or so it seemed although maybe I did drift off to sleep at some point only to be woken again by the next set of points!
From Huelva I continued to Ayamonte and took the small ferry across to Villa Real de Santo Antonio in Portugal and thence by local train to Faro. I took the late evening Rapido north which was quite exhilarating, just three coaches behind a CP class 50 clone, this took me to Barreiro for the ferry transfer across the Tagus to Lisbon - no direct trains across the river back then. My return to Madrid was on the day train from Lisbon in one of the RENFE T.E.R. sets.
Attached are some photos taken in Madrid on another occasion in 1988.
top - a YF at the head of a rake of WLs
middle - a close up of the badge on one of these, by now without the full '
et des grande express europeens' lettering
bottom- an older sleeper (possibly an Lx type (?)) looking as if it is now providing accommodation in an engineering train
Somewhere I do have a photo of the badge with full lettering which I will post when it emerges, also some of the Wagon Restaurant referred to in post 2.
