Netizens gave thumbs up for this

These little yellow men are actually railway contact network workers, and they are also called railway "Spider-Man" . The contact network is a power transmission line erected above the railway line to transmit electricity to the vehicles passing through it on a daily basis. The contact network workers eliminate potential dangers of the contact network through daily maintenance, and maintain the railway power supply equipment and driving safety.

Today I will take you to take a closer look

Overhaul of the contact network is usually scheduled during periods when trains are not running, sometimes lasting a few hours at a time and sometimes lasting for several days. This is what we often call railway “window” operations.

Contact network workers on railway contact network equipment

There are generally two ways to perform maintenance

V-shaped " skylight"

The V-shaped "skylight" means a one-way power outage on the up or down line of the railway. When maintenance personnel work on the line with power outage, it will not affect the traffic on the other line. The operation method is flexible and the operation time is relatively ample.

Vertical skylight

When the vertical "skylight" is operated, it is necessary to shut down the power supply of the railway transportation line both up and down. Its advantage is that it can realize the maintenance of contact network equipment quickly and over a large area.
