TWO-FREQUENCY COMBINATION TYPE AF TRACK CIRCUIT

It is shown that in the thyristor phase controlled car placed in practical service on the a-c electrified lines, higher harmonics are involved than in the conventional rectifier type cars and in consequence the existing amplitude-modulated AF track circuit is liable to make false action. A novel AF track circuit free from the interference of such high harmonics was developed.
