Tokaido Shinkansen in Japan was first HSR line in the world. It started in 1960s. Ever since then many countries have developed their own HSR networks Some known ones are France's TGV, Germany's ICE, Spain's Renfe and China's CRH.

Now, you may think “why are cities building expensive metros instead of much more cheaper trams of Buses?” there are 2 main reasons:   1) Capacity 2) Traffic Let me explain.   C apacity is the most important reason cities build metros.   Metros  can carry huge swaths of people and still operate every 2 or 3 minutes. Trams, on the other hand  have only about 3/4s the capacity of a metro....
