I don't know the answer, but you might like to try also asking on the forum especially about Travelling with Disabilities: tripadvisor.com/ShowForum-g1-i12336-Travelin…
Yes, the Jan Kiepura has a German wheelchair-accessible 2-berth couchette compartment, adjacent to an accessible toilet.
It has a spacious floor, table, and upper and lower couchettes, at one end of the couchette car. citynightline.de/citynightline/view/en/servi…
The price is as per a 6-berth couchette, so a good deal!
However, I think you'll need to book it by phone by calling DB (UK number 08718 80 80 66, lines open 0900-2000 Mon-Fri, 0900-1300 weekends)Edited: 5:52 am, March 04, 2013
