A standard passenger train car's capacity varies by design. A typical single-level commuter coach in the US or Europe usually seats between 70 and 90 passengers. However, bi-level (double-decker) cars, common on lines like Metra in Chicago or the TGV in France, can seat 120 to 150 people. If you include standing room—common in subway or metro cars during rush hour—a single car can hold over 250 people (though it will be very crowded!). In 2026, many high-speed trains utilize "articulated" designs where the space between cars is also usable, increasing total capacity. For luxury long-distance trains, the number is much lower; a sleeping car might only hold 20 to 30 people in private compartments to ensure comfort and privacy during the journey.
