Taking the metro when travelling in cities is often the easiest and most cost effective way to get around. Unlike taxis there is no haggling or fear of being ripped off and trains are much easier to figure out than buses where it can be difficult to know where to get off at the right stop. But it’s probably safe to say that most metros should be avoided during rush hour.
If you ride Tokyo’ s metro early enough on a Saturday morning you’ll see hung over businessmen still in their suits who didn’t quite make it home after a good night out. Many are chugging soft drinks purchased from Tokyo’s ubiquitous vending machines.
Mexico City’s metro is one of the cheapest and cleanest in the world and a subterranean market of sorts.
London’s aptly named tube is amongst the most expensive public transportation in the world. It was the world’s first underground metro.
New York City’s subway system will take you from the Bronx to Brooklyn for a few bucks. Despite rising fares it’s still the best deal in town.
