ABSTRACT:
In a brake signal converter device for a railway car a first signal conversion circuit is operative in response to a brake signal issued from the control stand of a first car in a form suitable for use by the first car and converts this brake signal to a form suitable for use by a second car and transmits it to the second car, while a first detector senses the brake commands issued at the first car and isolates the first car from these brake commands transmitted to the second car by means of a first switching section. In addition, brake signals issued from the second car are converted by a second signal conversion circuit to a form suitable for use by the first car and are transmitted to the first car, while a second detector senses the brake commands issued from the second car and isolates the second car from these brake commands transmitted to the first car by a second switching section.
