EN57 vs. EN71
What's the Difference?
EN57 and EN71 are both European standards that regulate the safety of toys. EN57 specifically focuses on the safety of electric toys, ensuring that they meet certain requirements to prevent potential hazards. On the other hand, EN71 is a broader standard that covers the safety of all types of toys, including chemical and physical properties. While EN57 is more specific in its scope, EN71 provides a more comprehensive set of guidelines for toy safety. Both standards are important in ensuring that toys are safe for children to play with.

Further Detail
Introduction
Electric Multiple Units (EMUs) are a common sight on railway networks around the world, providing efficient and reliable transportation for passengers. Two popular models of EMUs are the EN57 and EN71. In this article, we will compare the attributes of these two EMUs to help you understand their differences and similarities.
Design
The EN57 and EN71 EMUs have distinct design features that set them apart from each other. The EN57 is a classic design that has been in service for many years, featuring a boxy shape and a traditional interior layout. In contrast, the EN71 has a more modern and sleek design, with curved lines and a spacious interior. The EN71 also has larger windows, providing passengers with better views of the surrounding scenery.
Capacity
When it comes to passenger capacity, the EN57 and EN71 differ in their seating arrangements. The EN57 typically has more seating capacity than the EN71, making it a better choice for crowded commuter routes. However, the EN71 offers more standing room and space for luggage, making it a more comfortable option for longer journeys. Both EMUs are designed to maximize passenger comfort and safety, with ergonomic seating and ample legroom.
Performance
Performance is a crucial factor to consider when comparing EMUs. The EN57 is known for its reliability and durability, with a proven track record of service on various railway networks. It has a top speed of around 120 km/h and accelerates smoothly, providing a comfortable ride for passengers. On the other hand, the EN71 is a newer model with advanced technology and improved performance capabilities. It has a higher top speed of 160 km/h and faster acceleration, making it a more efficient choice for high-speed routes.
Energy Efficiency
Energy efficiency is an important consideration for railway operators looking to reduce their environmental impact and operating costs. The EN57 is known for its energy-efficient design, with regenerative braking systems that help to reduce energy consumption. It also has a lower overall energy consumption compared to older EMU models. The EN71 takes energy efficiency to the next level, with advanced propulsion systems and lightweight materials that further reduce energy consumption and emissions. This makes the EN71 a more environmentally friendly option for railway operators.
Technology
Technology plays a significant role in the performance and functionality of EMUs. The EN57 is equipped with basic onboard systems for passenger information and safety, such as CCTV cameras and emergency communication buttons. It also has manual controls for the driver, providing a more traditional operating experience. In contrast, the EN71 is equipped with state-of-the-art technology, including automatic train control systems and touchscreen interfaces for the driver. It also has advanced diagnostic systems that monitor the train's performance in real-time, allowing for proactive maintenance and troubleshooting.
Maintenance
Maintenance is a critical aspect of keeping EMUs running smoothly and efficiently. The EN57 is known for its ease of maintenance, with simple mechanical systems that are easy to access and repair. It also has a long service life, requiring less frequent maintenance compared to other EMU models. The EN71, on the other hand, has more complex systems that require specialized training and equipment for maintenance. However, it is designed with modular components that can be easily replaced or upgraded, reducing downtime and overall maintenance costs.
Conclusion
In conclusion, the EN57 and EN71 are both excellent choices for railway operators looking to provide efficient and reliable transportation for passengers. While the EN57 is a classic model with proven performance and reliability, the EN71 offers advanced technology and improved energy efficiency. Ultimately, the choice between these two EMUs will depend on the specific needs and priorities of the railway operator, whether it be capacity, performance, energy efficiency, or maintenance requirements.
