What radio frequency do railroads use?
between 160 and 162 MHz
Most railroads use a set of 97 frequencies between 160 and 162 MHz. Most operations are in “Conventional/Analog” mode, that means they do not usually use trunking, digital or other complicated modes. Most railfans will want to have a handheld scanner that you can use while standing line side.
What CB channel does Union Pacific use?
A common channel for Union Pacific is channel 020, and may be herad on the radio to goto Channel 20. Railroads on the radio still use the old channel number as opposed to the new numbers, where appropriate (ie “20” vs saying “020”).
Are railroad frequencies narrowband?
As of early 2010, railroads are known to be narrowbanding existing conventional radio use, and trunked-capable narrowband radios are being installed, but no trunked operation is known. Railroad communications must be highly interoperable.
What is an AAR channel?
AAR stands for: Association of American Railroads. This is an organization comprised of American and Canadian railroads.

10 Metres, 28.0 – 29.7MHz 10 metres is by far the widest of the HF bands and can seem very empty during the years of sunspot minima. However, there is often propagation to somewhere at many times, so it’s always worth checking and calling.
How do you call CQ 70cm?
Many repeaters (2m, 70cm) you do not have to call CQ. You can just say ” listening!”
How do Railfans know when a train is coming?
Railroads use what we call line-of-sight communications which means a scanner listener will hear the train crew when they are anywhere from 5 to 10 miles away. Line-of-sight reception is based on the radio transmit power.
How can you tell if a train is coming?
If a signal is lit up and shows all red lights, it is possible that there is a train approaching from “behind” the signal as shown in the photo above. If a signal is lit and shows a green light at the top, that means it is cleared for a train to approach from the lit/facing side, so a train may be coming.
Is CB channel 9 still monitored?
For a few others, listening to Channel 9 is a low- priority duty, and it is monitored only during quiet, nighttime hours. However, police do respond to telephone calls from CB-listeners who hear calls for help, and they still say that someone in trouble should try to get help on Channel 9 if they have a CB.
