As part of the European Sleeper, there are some coaches from EuroExpress. I was able to find those from Heris - they are pretty rare. Those coaches are rented for other charter trains, such as TCS. As it turns out, Piko just released the BR 101 in the TCS livery.
Prototypical train formation
I could not find a formation on www.vagonweb.cz, but there are plenty of photos on Flickr:
