People riding in the same car of a commuter train constitute a small group.true/ false
Alex_Xolod [135]

People riding in the same car of a commuter train constitute a small group. FALSE

A railroad car specifically built to transport passengers is known as a passenger railroad car, or passenger car (United States), also known as a passenger carriage, passenger coach (United Kingdom and International Union of Railways), or passenger bogie (India). A sleeping car, a baggage car, a dining car, a railway post office, and a prisoner transport car can all be referred to as passenger cars. With the development of the first railroads in the early 1800s, modest, barely modified freight cars were built as the first passenger cars. Early passenger vehicles were made of wood; but, in the 1900s, steel and then aluminum were used in place of wood for increased robustness.
