There is provided a track current suppression device. An exemplary device includes an input coupled between rails of a railway track and configured to receive an input voltage corresponding to a track current. The exemplary device also includes an amplifier configured to receive the input voltage and generate a cancellation current. The exemplary device also includes an output coupled between the rails of the railway track and configured to deliver the cancellation current to the rails with reversed polarity compared to the track current.
