A railway station is an important place for the communication system. It is a place where passengers get on the train and get down from the train. Every railway station has at least one building. In a railway station, there is a room for the station master, there is a booking room, there are rooms for ticket counters and there are the waiting rooms for the passengers. Every railway station has a platform. Big stations have more than one platform. A railway station is usually a busy place. Passengers are often seen in long lines to collect tickets. Some passengers take rest in the waiting room. Some passengers loiter here and there. Different types of vendors hawk their goods in the station. Some sell betel-leaf and cigarette, some sell nuts. One can also see some permanent shops in a railway station. It is a dear place for the beggars. They can sleep here at night. But the sight of the station has some changes with the arrival and departure of a train. As soon as a train comes to the station, passengers rush to get on it while many passengers get down. So, there is often a collision between the two groups of passengers-incoming and outgoing. However, as soon as the train leaves the station, it becomes less noisy. Thus, a railway station is a place of noise and activity.
