Advantages and disadvantages of building overground metro rail vs. underground ones.

Explanation:

Advantages:

  1. Cost effective option is overground as there is no need for provisions like lighting and air ventilation.
  2. Solar power can be utilized. Solar roof tops can be installed to power the station.
  3. Effective safety compared to underground. In case of fire, an overground station can be easily evacuated vs. underground stations.
  4. Easy maintenance.
  5. Easy to upgrade as space expansion is comparatively easier overground.

Disadvantages:

  1. Aesthetic issues. Changes to the skyline may not be aesthetic.
  2. Environmental factors. Weather can damage electrical equipments and disrupt communication.
  3. Extensive planning. It is challenging to design and implement the system in an existing concrete jungle.
