The invention relates to a bidirectional pre-stress concrete track plate with significant electric property and lower producing cost, and relative production line. Wherein, the track plate is a cuboid, with several preset structures; there are at least two layers of steel wires inside the track plate along its length and width directions; the steel wires in said two directions do not contact each other; said pre-stress concrete track plate are tensioned along the length and width directions; the production method comprises: spraying demoulding agent, feeding material, tensioning, coating concrete, vibrating, maintaining, tensioning and demoulding. The invention can overcome the defects of present technique, with simple method, while it can be used to build high-speed railway.
