About transport system there are 4 type of transport mode available basically all are important in their basis. the first one is air transport which fastest mode of transport when we need to go international destinations even domestic . it's costly than remaining transport moreover its provides you most safest and take less time among others will take lots of time. the best thing is you can feel the experience of fly through clouds in the air. the second one is water transport like ship , cruise ship , boat stuff like that's basically used for luggage shipping , expensive cars and many more thing which you import and export from other countries. so if you try to take a ride on ship it's make you feel cool breeze come on directly on your face and you will be able to more understand the water that's any time change the flow and peace everywhere no human land around you. you will be surrounded with blue water its sounds very well. the third one medium of transport is train. this is easy way to to take long journey through different places and city's with cozy train journey . it's easy to access and more convenient for passengers so far so good I think this would be a slogan of trains. where as , the forth one is public transport like taxi , uber , buses , rental car , auto etc. even though train is also a public transport but its apart from these kind of 4wheeler. mostly we used that for short distance and a city to another town . all medium are important in their separate place and different works. i'd love if someone were correct it..
