The first coupled running of vehicles at the CIWL International Sleeping-Car Company involved a Pullman with a kitchen and a Pullman without a kitchen (the kitchen was generally arranged in the middle). Coupled running was used to increase capacity by only having one crew work. Coupled running is still used today for sleeping cars. It was inaugurated on F-type cars (as in Ferry for the Paris-London links) due to their poor capacity, thereby enabling a driver to take care of two cars, and was reused on certain Car-Train links (Paris-Nice and Paris-Narbonne) as from 1991. A driver looks after an MU sleeping car and a T2, as there is less work on a car-sleeper train than with a normal train (fewer reservation problems, few breakfasts, as these are normally taken care of on arrival while the cars are being unloaded...).
