Business Class is located in the two train cars closest to the engine (locomotive). The train is typically configured like this: Locomotive, two Business Class cars, Café car, and Unreserved Coach cars.

In 2026, the location of Business Class on a train depends on the operator, but it is typically found at the very front or the very back of the train set. On high-speed networks like China's CRH or Italy's Frecciarossa, placing Business Class at the ends of the train ensures a "quiet zone" with no through-traffic from passengers walking to the dining car or other coaches. In some configurations, Business Class (or its equivalent, like "Executive" or "Premier") occupies a dedicated carriage near the engine for maximum stability and privacy. These carriages are often separated by automatic glass doors and feature a 1+2 or 1+1 seating arrangement. A 2026 "pro-tip" is that on many modern European "tilting" trains, the center carriages are actually the most stable; however, for the sake of exclusivity and reduced foot traffic, the premium cabins remain anchored at the train's extremities.
