Wiring groove for rail vehicle

The invention discloses a wiring groove for a rail vehicle. The wiring groove comprises a bottom plate, and a plurality of ventilation holes are formed in the bottom plate. The wiring groove is characterized in that a plurality of isolation plates are connected to the bottom plate in an inserted mode, plate grooves are formed in the two opposite vertical planes of every two isolation plates, an n-shaped cover plate is arranged between every two isolation plates and is inserted into the corresponding plate groove to form a wiring groove space, and an isolation cover is arranged in each wiring groove space. The isolation plates and the cover plates can be quickly inserted through a groove body structure, and the isolation covers can be quickly closed through a shaft structure; the wiring groove is provided with the wiring groove spaces so that strong-current, weak-current and signal wiring can be carried out separately, wiring efficiency and accuracy are improved, and meanwhile, electromagnetic interference can be well prevented through the isolation plates and the isolation covers.
