Overall, most cities shared a similar number of lines and total length, while the New York City Subway showed a dramatic difference compared to the others. In terms of the cost of single ticket, the price and annual journeys vary with an enormous range.
First of all, the lines and the total length of the underground systems exhibited marked differences. the New York City Subway and Beijing Subway owned 24 lines and 19 lines respectively. However, the London Tube and Mexico City Metro showed a significant contrast as they have only 11 lines and 12 lines respectively.

Under the big difference on the price, the annual journeys had showed a total reverse compared to the cost. The New York City Subway travelled 1.65 billion annually and the Beijing Subway had travelled 3.6 billion through out the year. Other metro systems seem to have similar prices and annual journeys.
