[0013] 1. In the utility model, a wire trough specially used for railway passenger cars is provided, and the wire trough box with an original fixed internal partition structure is split into a left wire trough box, a middle wire trough box and a right wire trough box. It can be assembled according to the number of wire harnesses fixed on site, avoiding waste of space, being more practical, and being simple to insert and install.

[0014] 2. In the utility model, a wire trough specially used for railway passenger cars is provided, and a plurality of groups of elastic clamps with the same intervals are arranged inside the left wire trough box, the middle wire trough box and the right wire trough box. When wiring inside the wire trough box, the wire harness is clamped in sections inside the elastic clamps.
