The rear rail serves as a vital component in a vehicle's structure by providing a connection point between the rear wheels and the main framework of the car. This part is typically aligned with the vehicle's rear suspension system and plays a critical role in maintaining structural integrity, ensuring proper alignment, and supporting the weight of the vehicle at the rear end. It also helps absorb and distribute stresses generated during operation, such as cornering or when driving over uneven surfaces.

When considering this context, the rear rail's primary function is to connect and support the elements of the rear axle and wheels, thereby contributing to the overall stability and performance of the vehicle. Other components, such as the strut tower or apron, front rail, and suspension crossmember, are important in their respective functions but do not directly connect the rear wheels to the car's framework in the same way the rear rail does.
