Public transport is a form of transportation that is available to the public, usually for a fee. It includes a variety of transportation options such as autobuses, omnibuses, buses, trams, and trains. Autobuses are large motor vehicles that can carry many passengers at once. Omnibuses are similar to autobuses but are usually smaller and can be used for shorter distances. Buses are also motor vehicles that can carry many passengers, but they are typically smaller than autobuses. Trams are rail-based vehicles that run on tracks and are powered by electricity. Trains are also rail-based vehicles, but they are powered by diesel or electric engines and can travel long distances. All of these forms of public transport provide an efficient and cost-effective way of getting around.
