Написать маленький текст о легком метро и о городской электричке, которое находится в лондоне. 30

hello my essay about London's underground. i never was there but i saw many movies and cartoons with it. how i know the different between subway and underground its because subway is American English

and underground is British English

its really good to use because for cheap price you can go from A point to B. Many people use it everyday and its really very useful for us.
