In the Nostalgie-Istanbul-Orient-Express, the diaphragms are lined with blue velvet and a blue carpet. This makes the passage between two cars very pleasant. I didn't find out whether this was already done in the early time of these cars or is an idea of the Reisebüro Mittelthurgau. 3rd February 1995.
