Qatar World Cup 2022 Stadiums Progress

The Qatar World Cup 2022 will give Qatar and the Middle East a set of world-class stadiums which will become magnets for future events of every kind.

Most of the venues will feature modular designs to allow excess seating to be removed post-2022. These seats will be donated to football projects around the globe, helping to spread the love of the game and spurring its worldwide development. The stadiums' reduced capacities will create arenas suitable for local football and other events, guaranteeing a vibrant atmosphere.



The areas surrounding the stadiums will become focal points for their communities. They will include high-quality sporting facilities, parks, schools, transport links, shopping centres and places of worship. These amenities will help the country to achieve the development goals set out in the Qatar National Vision 2030.

Railway Engineering: An Integral Approach

Have you ever wondered what it takes to get your train on the right platform at the scheduled time every day?

Journey with us into the world of rail - a complex system that connects people, cities and countries.

Railway systems entail much more than a train and a track. They are based on advanced technical and operational solutions, dealing with continuously changing demands for more efficient transport for both passengers and freight every day. Each system consists of many components that must be properly integrated: from trains, tracks, stations, signaling and control systems, through monitoring, maintenance and the impact on cities, landscape and people. This integration is the big challenge and the source of many train delays, inconvenient connections and other issues that impact our society.

This engineering course attempts to tackle those issues by introducing you to a holistic approach to railway systems engineering. You will learn how the system components depend on each other to create a reliable, efficient and state-of-the-art network.

We will address questions such as:

• How do railways work and how did they evolve over time?
• How do different components of the railway system interact?
• What is the effect of railways from an urban, social and economic point of view?
• What can be done to improve the monitoring and maintenance of tracks?
• How are timetables designed in a way that balances passenger demand with the capacity of the railway and is adaptable to handle unexpected disturbances?
• How to prevent and deal with disturbances caused by external factors?
• How does the design of railways influence their performance over time?

A new serious game has been designed for this course to guide you through the process of decision making while building a rail network and maintaining it. Cities have to be connected in an ever-changing setting, dealing with wear, capacity, developments and disturbances. How will your choices affect the performance of the system?

What you'll learn

• Identify the name and function of the main railway network components
• Evaluate the influence that railways exert on their environment and vice versa
• Explain the different methods of train control and their effect on timetabling and safety
• Understand the effects and the internal and external factors of disturbances on railway operations
• Identify the different methods of dealing with system degradation and the effects of interaction between the components
• Explore the state-of-the-art and future developments of railway systems

Are you an expert in the field?While this MOOC introduces different aspects of the railway network, if you want to go into more detail, gain advanced knowledge and expertise for your daily work, you can enroll in our follow-up online professional education courses.
