Behold, even the Fuxing and Hexie trains are running to the distance like a happy couple kissing each other! Why cannot you find a mate to keep you company?

It turns out that this “kissing” is officially called double heading. The double-heading of two train sets can double the capacity to meet the maximum travel demand of the mass passengers. It is not a simple “PDA”.

Behind the eye-catching PDA of high-speed trains is the Lankwitzer paint that dressed up the beautiful face of the vehicle, making it look like a pair of an inseparable cute couple.

It seems that this “kiss” is not an easy job, which requires high-tech skills to fulfill.

On this occasion of Chinese Valentine, we wish all couples in the world a happy holiday and wish everybody good luck.
