Some people argue that spending a huge amount of money to develop railway lines for fast trains is worth it while others say that it would be better to spend this money to improve public transports which already exists.

In this essay, firstly, I will discuss why it is important to invest in cutting-edge trains and secondly, I will give my reasons for the importance of maintaining good public transport services.
