CLEAN : Ethiopia tests Sub Saharan Africa's first light rail system

The video tutorial covers an introduction to a project, discusses the estimation of headway time between trains during peak hours, and explains how power fluctuations are managed in a light rail system. The system is designed with a Loop in Loop out scheme to ensure continuous power supply even if one substation fails.

What is the estimated headway time between trains during peak hours?

• 90 minutes

• 60 minutes

• 45 minutes

• 30 minutes

What is the purpose of the dedicated line connector to the National Grid?

• To increase train speed

• To reduce ticket prices

• To enhance passenger comfort

• To prevent power fluctuations

What scheme is used to design the power consumption for the light rail system?

• Direct Current Scheme

• Loop in Loop out Scheme

• Alternating Current Scheme

• Single Line Scheme

What happens if there is a power cut in one of the traction substations?

• The entire system shuts down

• Trains run on backup batteries

• The other substations compensate for the power loss

• Passengers are evacuated

What is the main benefit of the Loop in Loop out scheme?

• Increased train speed

• Reduced maintenance costs

• Avoidance of power interruptions

• Lower energy consumption
