Improving Passenger Comfort: Why we need good trains and sound track - Q&A with Mani Entezami, University of Birmingham

Ahead of our Improving Passenger Comfort seminar, we caught up with Mani Entezami, Senior Research Fellow, Railway Condition Monitoring at the University of Birmingham.

Mani discusses his role and involvement with regards to improving ride quality on the railway, the challenges of improving ride comfort and quality in new and existing rolling stock, what he is looking forward to at the event and why it is important for engineers to attend.

Q: Please could you briefly explain your role, involvement, and experience with regard to improving ride quality on the railway and this event?

Mani Entezami (ME): As a dedicated researcher, my work has involved close collaboration with train operators and track teams to deepen our understanding of the complex relationship between ride comfort and track geometry. Through a comprehensive study, I have investigated the various factors that contribute to this relationship, including issues related to both trains and tracks. By leveraging advanced analytical tools and state-of-the-art technology, I have been able to identify key areas for improvement and develop innovative solutions that address these challenges, ultimately enhancing the safety and reliability of rail transportation.

Q: What, in your experience, has been the biggest roadblock for applying research to improve ride comfort and quality in new and existing rolling stock?

ME: Throughout my research journey, I have been incredibly fortunate to have had the unwavering support and cooperation of both the train operation and track maintenance teams. Their willingness to share valuable information has been instrumental in producing high-quality research that addresses critical issues in the field.

Despite this support, the reality is that securing funding for research in this area can be challenging, especially when funding is not fully covered. As an academic, I have encountered some difficulties along this route. However, I remain committed to pursuing innovative solutions and developing a deeper understanding of the complex issues that impact rail transportation. With continued collaboration and support, I am confident that we can overcome these challenges and make meaningful progress towards safer, more efficient rail transportation systems.

• Predictive maintenance systems: Predictive maintenance systems can help to prevent breakdowns and improve the reliability of trains, leading to a more comfortable and stress-free travel experience for passengers.
• Smart lighting and temperature control: Intelligent lighting and temperature control systems can be used to create a comfortable and relaxing environment inside the train.
• Air filtration systems: High-efficiency air filtration systems can help to reduce the spread of airborne viruses and improve air quality inside the train.
• Personalized entertainment and information systems: Personalized entertainment and information systems can be tailored to meet the individual needs and preferences of passengers, providing them with a more enjoyable and engaging travel experience.
• Noise cancellation technology: Noise cancellation technology can help to reduce the level of ambient noise inside the train, making it more peaceful and relaxing for passengers.

Overall, these technologies and applications have the potential to transform the passenger experience, making train travel more comfortable, convenient, and enjoyable.

Q: Who else are you most interested in hearing from on the programme or at the event?

ME: The perspectives of different stakeholders in the railway industry on passenger comfort are crucial in shaping the future of railways.

• Train operators play a critical role in ensuring that passengers have a comfortable and enjoyable travel experience. They are responsible for managing the day-to-day operation of the railway system and ensuring that the trains run on time, are well-maintained, and meet the required safety standards. This also includes the drivers and how they maintain the ride to meet passengers expectations. 
• ROSCOs (Rolling Stock Operating Companies) are responsible for leasing and maintaining trains to train operators. They have a significant influence on the design, performance, and quality of the rolling stock. ROSCOs play an essential role in ensuring that the trains are comfortable, safe, and meet the required standards.
• Train manufacturers are responsible for designing and producing trains that meet the required specifications and standards. They have to take into account factors such as passenger comfort, safety, and efficiency in their design and manufacturing processes. Train manufacturers also have a role to play in innovating new technologies and materials that can improve passenger comfort and the overall performance of the railway system.
• Infrastructure design and maintainers, they play a crucial role in ensuring that the railway system is safe, reliable, and efficient. They also have to take into account passenger comfort when designing and maintaining railway infrastructure.

Therefore, understanding the perspectives of these stakeholders on passenger comfort is essential in shaping the future of railways. By collaborating and sharing ideas, it is possible to develop innovative solutions that enhance passenger comfort, improve operational efficiency, and ensure the long-term sustainability of the railway system.

Q: Why is it important for engineers to join this event?

ME: 

• Networking: Events provide an opportunity for engineers to connect with other professionals in the field, exchange ideas and experiences, and build professional relationships. These connections can lead to new collaborations, partnerships, and job opportunities.
• Knowledge sharing: Seminars and conferences offer access to the latest research, technologies, and best practices in passenger comfort, as well as insights into emerging trends and challenges. Attending conferences can help engineers stay up-to-date with industry developments, broaden their knowledge, and develop new skills.
• Professional development: Many events offer workshops, training sessions, and keynote speeches from industry experts, which can help engineers develop new skills and deepen their knowledge in specific areas. These opportunities can contribute to the engineer's professional growth and enhance their career prospects.
• Influence: Engineers play a crucial role in ensuring that passenger comfort is prioritized in the design, development, and maintenance of transportation systems. By participating in passenger comfort events, engineers can influence industry standards, policies, and practices to improve the comfort, safety, and overall experience of passengers.
