What exactly does high-speed rail ground handling do? There are some details, I hope someone who knows can help!

There are many railway professions. High-speed rail ground staff may be cleaning staff, or they may be public engineering, electrical, train maintenance, machine maintenance, or signal traffic. It depends on what kind of professional personnel you are.

The work of high-speed rail ground attendants is relatively easy. In terms of wages, it depends on whether they are contract workers, labor dispatch workers, or regular workers. The wages of contract workers or labor dispatch workers are lower, but those of regular workers are higher. Ground handling is to ensure the safety of the EMU on-line operation and carry out maintenance operations. High-speed rail ground handlers sometimes need to work night shifts, which is safer than aviation ground handlers.

Expansion: High-speed Railway

High-speed railway is a railway system with high railway design speed that allows trains to run at high speeds. The world's first formal high-speed railway system was Japan's Shinkansen, which was completed and opened to traffic in 1964. The design speed was 200km/h, so the initial speed standard for high-speed railways was 200km/h. Later, with the advancement of technology, trains became faster. Different countries in different eras had different definitions of high-speed railways, and stipulated detailed technical standards for their respective high-speed railway levels based on their own national conditions. The train speeds, railway types, etc. involved were different. All the same.
