Sleeping-car of the RZD (Russian railways), of the UIC-Z type built in 
the 90s. This type (26.4 m long, with UIC505 loading gauge) was 
designed for international service, the gauge can be changed by 
exchanging the bogies. These air-conditioned, airtight cars reach
200 km/h. They have replaced the older 24.5 m cars with coal heating.
