There are four Economy Class coaches per OBB train and five coaches in a standard Czech Railways Railjet train
. The number of coaches depends on demand on the specific route mostly.
The seating plan in Economy Class is relatively standard for the high-speed trains you may see in Europe. There are 2+2 seats placed in front of each other, and the rest are designed for 4 people sitting together.
Meals and snacks are not included in the Economy Class fare but can be purchased separately from the train's restaurant.
