A method for indicating a status of a railroad switch is configured for use in un-signaled (dark) territory utilizing vital audio messages. In one embodiment, the method comprises receiving a DTMF signal from a railway vehicle, initializing control of the switch, and triggering the reporting of a correspondence condition through vital relays or other electronic components.

A remotely activated rail switch system is disclosed herein that is configured to permit the remote control of a railroad switch. The rail switch system may include at least a connecting clamp configured to removably attach to any standard size rail switch throw arm, a motor, an interconnect member between the connecting clamp and the motor, and a transceiver. In various embodiments, the remotely activated rail switch system may be installed without making any modifications to the existing rail infrastructure. For example, the rail switch system may be installed without any welding, digging, and/or other civil construction. Rather, the remotely activated rail switch system may be installed by simply (or only) clamping a frame or body of remotely activated rail switch system to wooden ties adjacent a rail switch and attaching the connecting clamp of the remotely activated rail switch to the throw handle of the switch.

Disclosed herein is a method for indicating a status of a railroad switch used in un-signaled (dark) territory utilizing vital audio messages. In one embodiment, the method comprises receiving a DTMF signal from a railway vehicle, initializing control of the switch, and triggering the reporting of a correspondence condition through vital relays or other electronic components.

The system provides a railroad switch for use in un-signaled (dark) territory. In particular, the system includes a plurality of audio messages maintained on a discrete audio board, where a DTMF signal is validated, initializes the control of a switch, and triggers an audio board to report a correspondence condition, where the output of the audio board is checked by a relay status.
