The invention discloses a rail train and a device cabin thereof. The device cabin comprises a device cabin framework and a skirt plate. An air opening is formed in the skirt plate. A filter screen is arranged on the portion, corresponding to the air opening, of the inner side of the skirt plate. A slide way is arranged on the inner side face of the skirt plate and extends in the longitudinal direction of a vehicle body. The filter screen is arranged in the slide way in a sliding mode. The outer contour of the filter screen is of an arc-shaped structure protruding towards the skirt plate. By means of the arrangement mode of the filter screen in the device cabin, the occupancy rate of the filter screen for the width space of the vehicle body can be decreased, and space utilization rate of the device cabin and the maintenance convenience of devices in the device cabin are increased. In addition, on the premise of not changing the height of the device cabin, the available filter area of the filter screen of the arc-shaped structure is larger than the filter area of the filter screen of the straight plate form, and therefore the device ventilation amount can be effectively increased, and the working performance of the devices is conveniently improved; in addition, the filter screen in the device cabin can not fall out of the slide way, and the personal safety of operators is conveniently improved.
