A supplemental power source connectable to a standard railroad track switch power source. A pair of electrical connectors (A) form a supplemental power source circuit input. Another pair of electrical connectors (B) form a supplemental power source output and are configured for connection to a standard railroad track switch. An electrical conductor connects a first one of the supplemental power source output connectors (B) to a first one of the supplemental power source input connectors (A). A diode is connected between a second one of the supplemental power source input connectors (A) and a second one of the supplemental power source output connectors (B). The diode is connected to prevent current flow to the standard railroad track switch power source. An ultracapacitor is electrically connected between the electrical conductor and the second one of the supplemental power source output connectors (B).
