Do you want to hear cool real-life train sounds? If so, you're in luck! This app features amazing train sounds that will make you feel like you're really there! Whether you're standing at the platform as the train approaches or waiting at a railroad crossing, trains can be noisy machines! Older types of trains, such as coal trains and steam locomotives in particular make many exciting and unique sounds - from the characteristic choo-choo of the train's horn to the clickity-clack or metallic screeching of the wheels against the railroad tracks. And don't forget the sound of the engine going chugga-chugga as it moves the train along! Depending on the type of train, the sounds you will hear will be quite different! Trains are an important mode of transportation for both people and things. Passenger trains carry people to destinations near and far, while freight trains move large amounts of cargo in boxcars or other types of carrier cars. Trains are so popular that they are even a favorite children's toy - kids love playing with toy trains and building model tracks! Explore train sounds to experience noises you've never heard before! Babies and kids in particular will delight as they learn the exciting sounds of the train station!
