The CR450 also prioritizes passenger comfort, aiming to offer a smooth and quiet ride, even at 400 km/h. Advanced noise-reduction technologies ensure that the interior noise levels are comparable to those of the 350 km/h trains, providing a peaceful travel experience.

A standout feature of the CR450 is its exceptional energy efficiency. The train's running resistance has been reduced by 22 percent and its weight cut by 10 percent, leading to improved fuel efficiency. These optimizations help minimize energy consumption despite the increased speed.

The train's interior has been redesigned for added comfort and convenience, increasing cabin space by 4 percent. Adjustable luggage racks and a versatile storage area cater to passenger needs, including accommodating bicycles, wheelchairs and other items. These innovations were made in anticipation of potential regulatory changes in passenger transportation.
