The invention provides a vehicle-mounted transformer, a box body structure of the vehicle-mounted transformer and a railway vehicle. The box body structure is used for being installed on the outer side of a vehicle, a transformer coil structure is arranged in the box body structure, a heat dissipation structure is installed on the outer side of at least one box body wall of the box body structure, and a coil cavity and an outer side cavity are formed in the box body structure; the coil cavity is formed in a space for accommodating a transformer coil structure, and cooling liquid in the coil cavity is used for being in contact with a coil in the transformer coil structure; the cooling liquid inlet of the box body structure is communicated with the cooling liquid outlet of the box body structure through the coil cavity and the outer side cavity in sequence; when the box body structure is installed on a vehicle, the outer side cavity is located on the side, away from the vehicle, of the coil cavity. The cavity wall, away from the coil cavity, of the outer side cavity is a box body wall provided with a heat dissipation structure.
