A feeding apparatus for railway is provided to reduce an induced current, to constantly supply power at the same time, and to improve power transmission efficiency, by comprising: a power supply unit that supplies current; an inverter that receives current from the power supply unit and converts into a first high frequency current and a second high frequency current; a first feed line that receives the first high frequency current from the inverter, creates a magnetic field, is placed in between rails, forms a first point of intersection by crossing, and offsets an induced current flowing in the rails; and a second feed line that receives the second high frequency current from the inverter, creates a magnetic field, is placed in between rails, forms a second point of intersection by crossing, and offsets an induced current flowing in the rails, the second point of intersection being placed in between the first point of intersection.
