One way to solve problem of congestion in cities is to build sky trains which run overhead rather than on or under the ground. What are the advantages and disadvantages of using this solution to solve congestion?

It is clear that

traffic jams are becoming a major problem in metropolitan areas. It is believed that

this

issue can be tackled by constructing overhead railway stations which host sky trains

instead

of the trains that run on the ground or under it. In

this

essay, I will discuss the benefits and drawbacks of

this

view with examples. On one hand, building railway points on or under the ground requires a huge amount of space.

This

space can be utilized in an even better way by building overhead metro stations.

For instance

, if the government decides to start the sky train service, the land on the ground can be used to build additional highways which can play an important part in reducing car congestion.

In addition

,

this

can generate a sizeable amount of revenue as

this

mode of transport is often considered a huge attraction around the world.

On the other hand

, the construction of

this

transport over a large distance can cost an extortionate amount of money.

Due to

this

, the maintenance cost is

also

high. Because the service cost is high, citizens

also

have to pay huge ticket prices.

Furthermore

, these cables are more vulnerable to adverse weather conditions as compared to the others.

This

is because of the height at which they operate.

For example

, it is commonly seen that more servicing is carried out during the monsoons

instead

of other seasons. In conclusion,

although

there are various advantages of adopting overhead train transport

such

as reducing congestion or using the space available for other productive things, there are

also

a few disadvantages attached to it like the construction and maintenance costs and the effects of bad weather.
