The tube is a great method of transportation. Subways are ideal because they are underground and don’t have to deal with any of the traffic from above ground. They also don’t have to be bogged down by the actual design of the city and can directly link all of the most popular and central spots. Perhaps the most interesting part of the tube is the culture around it. London had a very unique subway ettiquette. The ettiquette allows for it to be incredibly efficient. It truly is an important part of the city which just lies underground. I definitely envy London for having the tube while in Columbus we just have the COTA bus system which pales in comparison.
