The first-class passengers can make their way along the train past the second-class passengers and past the restaurant car into the first-class accommodation at the end of the train.
They often have a dining car or restaurant car to allow passengers to have a meal during the course of their journey.
The trainset included two power cars, three intermediate cars and one service car second class, one restaurant car and one intermediate car first class.
The first class cars and the restaurant car are spared the electrical noises from the asynchronous motors.
Originally, the trainsets were coupled from 13 intermediate cars: four first class, restaurant car, service car and seven cars second class.
That is that the accommodation in the first-class and third-class restaurant cars should be combined and the space thus available divided between smokers and non-smokers.
Most railway restaurant cars are already divided into first-class and third-class.
Restaurant cars cannot be provided as long as there is a shortage of seating accommodation.
