Abstract
An electrical device not only controls train signals as trains advance, but also alters the voltage in the tracks leading up to the signals so that the trains will actually stop at a red signal, slow at an amber aspect and continue on at full speed when the signal is showing green. The electrical device of the present invention can change the “block signal” from “green” to “red”, thereby signaling the engineer behind the train to come to a stop. In addition, the electrical device can simultaneously change the voltage in the tracks to stop the approaching train at the red signal. Only when the forward train has cleared will the approaching train get a clear signal and voltage to resume its forward progress.

A train control device comprising:
- a first relay and a second relay, the first and second relays being four-pole, double throw relays;
- a voltage input providing a first voltage input, a second voltage input and a third voltage input;
- first, second and third signal outputs adapted to send power to a signal;
- and
- a train power output adapted to send train power to a train block based on train position;
- wherein the third voltage input is a stop signal;
- and
- wherein the stop signal is sent to the train power output when a train is present in an immediately forward block.
