A farm rail system comprises a farm rail and a side station power line (1)； the farm rail comprises a group of two reinforced concrete tracks (82) arranged in a farm in parallel, and shapes thereof comprise arched and straight shapes； centre line states of two adjacent straight farm rails that are connected end-to-end comprise concentric and non-concentric； the side station power line (1) comprises several shell bodies (2) that are mutually connected end-to-end, an insulation material layer and a wire (4), and the side station power line (1) is arranged along the tracks (82) and electrically connected to a power grid (30)； also comprised is a power receiving module assembly (6), and the power receiving module assembly (6) comprises a chassis (14), a fixed electrical connector (13), several conductive column plates (12) and a sliding power receiving block (11)； the sliding power receiving block (11) is in contact with a surface of the wire (4)； the chassis (14) is connected to the shell bodies (2) in a matching and rolling way through a wheel set or an electric wheel set (18) and moves along a centre line direction of the shell bodies (2)； and the wire (4), the sliding power receiving block (11), the power column plates (12) and the fixed electrical connector (13) form a circuit branch. The farm rail system is a track system that is insensitive to thermal expansion and contraction, thus ensuring that the shell bodies (2), an insulation material pipe and the wire (4) can still work reliably in a long term when repeatedly experiencing the thermal expansion and contraction caused by rapid temperature changes of more than 80°C brought by sun exposure and large-current heating of the wire.
