The utility model relates to a bi-directional pre-tensioning transverse single-layer prestress track slab. The bi-directional pre-tensioning transverse single-layer prestress track slab comprises a track slab body, longitudinal pre-tensioning prestress steel bars and transverse pre-tensioning prestress steel bars are arranged inside the track slab body respectively in the longitudinal direction and in the transverse direction, the longitudinal pre-tensioning prestress steel bars are distributed on an upper layer and a lower layer of the track slab body in the thickness direction, and the transverse pre-tensioning prestress steel bars are distributed on a single layer of the track slab body in the thickness direction and are arranged between the two layers of longitudinal pre-tensioning prestress steel bars. Due to the adoption of the structure, the strength and the service life of the tack slab are guaranteed. The way how the longitudinal pre-tensioning prestress steel bars and the transverse pre-tensioning p
