The subway travels at fast speed under the ground.

What is your question?

It does, doesn't it?

That's correct! The subway is a form of public transportation that often operates underground, allowing it to travel quickly and efficiently through cities. However, it's worth noting that not all subways travel exclusively underground. Some subway systems have sections that run above ground or at street level.

If you are interested in learning more about the speed of subways, you might wonder how fast they actually move. The speed of a subway can vary depending on several factors such as the city, the design of the subway system, and local regulations. However, a typical subway train can reach speeds of around 50-60 miles per hour (or 80-100 kilometers per hour).

If you have a specific subway system in mind, finding its top speed can be as simple as doing a quick search online. Search for the subway system's name and "top speed" or "maximum speed" to find information about how fast it travels. You can also check with the local transit authority or the subway's official website for official statistics regarding the train's speed.
