But soon most of these kings, great dukes and princes possessed their own private coaches or trains. In other cases the railway companies provided such coaches and rented them to royalty. Complementary to those private coaches and trains were private reception rooms in the station buildings and in some cases even private railway stations for the exclusive use of these privileged few. A well-preserved example is Potsdam Park Sanssouci railway station, a railway station for the use of Emperor Wilhelm II. near his summer palace, the New Palace in Potsdam.
