"Governments should spend money on railways rather than roads. To what extent do you agree or disagree with this statement?"

My essay

Enhancing public facilities is government's responsibility. It is argued that railways should be preferred being preserved and upgraded to roads. However, it seems to me that both roads and railways should be spent money on in contemporary. The reasons for this are as follows.
First of all, it is an undeniable fact that not only roads but also railways are for society's benefits. Trains which run on railways are public transports. Using train for moving purpose is so affordable that many people choose it. Enhancing railways would make train services working better. This helps population's saving rises, thus, they can spend money on other demands to make their lives more comfortable. Another advantage is that if people go by train more, thanks to railways upgrading, there will be less private transport utilization. The less private cars and vehicles move on the roads, the less emission produces, which means the air pollution can be reduced.
On the other hand, roads are convenient for those whose private transports. As the number of cars and vehicles increases, upgrading roads helps to reduce traffic problems such as accidents or rush hours, which means that people can reduce spending money on restoring accidents' damages or go home in shorter time. Besides, economic also takes advantage of road enhancement. It will be easier to transport commodities. This leads to a growth in trading.
In summary, it is sensible to conclude that government should invest in both roads and railways because each access has its own advantages.
