Abstract
Un método y un dispositivo capaz de determinaciones fiables y precisas de predicción de trenes que tengan en cuenta y superen los problemas asociados con las condiciones cambiantes del balasto. El método y el dispositivo detectan la presencia de un tren en un área de aproximación que se basa en una característica de los rieles medida en relación con una primera frecuencia de medición transmitida a lo largo de los rieles. Si existe una condición, tal como una condición del balasto, que pueda afectar a la característica de los rieles, el método y el dispositivo detectan la distancia y la velocidad del tren que se basan en una característica de los rieles medida en relación con una segunda frecuencia de medición transmitida a lo largo de los rieles. De lo contrario, la distancia y la velocidad del tren se determinan en base a la característica de los rieles medida en relación con la primera frecuencia de medición.
