Most passenger and commuter trains have to call out signals. Many class one railroads have also now required this as well, depending on traffic volume. Places like the San Bernardino and Cajon Subs there is too much traffic to have all that on the radio. Amtrak and Metrolink are still required to call signals on the radio.
