Description

Technical Field

[0001] The invention relates to the technical field of traffic, in particular to a ground trough type lifting guardrail. Background Art

[0002] There are almost no protective devices on the edges of the railway tracks at train platforms, and people often slip or fall off the platforms accidentally, causing casualties. Currently, trains cannot be controlled as precisely as subways, and cannot start and stop at designated locations.
