The invention relates to a test device for determining a cold region tunnel temperature field under the action of train wind. The device comprises a tunnel model box, a temperature control box, a train model, a temperature sensor and a data acquisition system. The tunnel model box comprises a bottom plate, a side plate, a baffle plate, a supporting plate and a foam heat insulation plate; a lining structure is arranged between the two baffles, and the space between the lining structure and the foam heat insulation plate is filled with soil. A train model is arranged in the lining structure; temperature control boxes communicated with the lining structure are arranged at the two ends of the tunnel model box respectively; arranging temperature monitoring sections at equal intervals in the axial direction of the tunnel model box, and arranging a plurality of temperature sensors on a lining structure and a soil body at equal intervals in the radial direction of a tunnel on each temperature monitoring section; and
