Abstract

Perfeccionamientos en sistemas centralizados de control de tráfico para líneas férreas, caracterizados por un sistema eléctrico de indicación a distancia para registrar en una oficina central indicaciones de condiciones variables procedentes de una serie de desvíos de la línea alejados de dicha oficina central y conectados a la misma por un canal de comunicación, y porque cada desvío de la línea está preparado para transmitir una señal distintiva a la oficina central al ocurrir un cambio en las condiciones del mencionado desvío de la línea; la oficina central responde a las mencionadas señales para cambiar las condiciones de transmisión en el canal indicado, y cada desvío de la línea responde al cambio de las condiciones de transmisión en dicho canal para colocarse fuera de comunicación con la oficina central si en el mencionado desvío de la línea no ha ocurrido ningún cambio de condición.
