Question

Answer 2

Well, it depends on what you actually qualify as a bullet train. Slovenia is the smallest country with a "high speed" train, which runs at an excess of 200 km/h (125 miles per hour).

Yet, there are other small nations that are planning their own bullet trains. For example, Trinidad & Tobago, a Caribbean nation better associated with calypso music, is building a high speed line.
