Railroads


Listed below are standard frequencies used by railroads in the United States. Similar/same frequencies may be used for crossboarder operations with Mexico and Canada. The American Association of Railroads (AAR) has assigned channel numbers to each standard voice radio frequency.

Such channel numbers are used with railroad radios and are commonly referred to by field personnel. Locomotive radios are able to select individual transmit and receive freqenices as needed. Sometimes this can be heard as "Go to 20-90". Standard practice is simplex operations, with the same channel number. 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 approrite (ie "20" vs saying "020").

The AAR standard for digital voice radio uses the Kenwood/ICOM NXDN/Nexedge digital format in 6.25KHz spacing. There is no mandate to use digital, but those locomotive or operations that are required to interchange with other railroads must use NXDN, if digital radio is used.

Regional or smaller/tourist railroads have been known to use channels or trunked radio systems outside of the AAR plan. If interchanging with another railroad, the AAR standard will be used.

Amtrak oustside of its own rail lines can be found on the host railroad's radio channel. Station operations may or may not be on a separate channel. Trains from another railroad company training on another railroad will be found on the host railroads channels (IE a Norfolk Southern train detouring on CSX)

Railroad radio operations are additionally found in each states railroad section

Railroad Operations
AAR 002-097
These channels are part of the original AAR band plan, and are widely used in the United States. After the narrowband mandate, AAR relabeled the channels with a 0 (zero) to indicate that the channel is now narrowband. Channel 24 (25 wide) became 024 (12.5 wide) and the frequency remained the same. Channels 002-006 are used in Canada and do not exist in the US band plan

AAR 107-196
Channels listed are an addition to the AAR band plan when narrowbanding took effect. These are "splinter channels" and reside in between the existing AAR channels. Great care must be taken when submitting information to the database as these are not widely used. Interference, poor receivers and the such may cause a scanner user to believe that one of these 100 series channels are in use when in fact it is a 007-097 series channel being used

AAR 307-487
These channels are the standard railroad digital channels using NXDN modulation at 6.25kHz spacing. No RAN codes are programmed on these standard channels. Site specific exceptions are possible as those radios/channels are only used at a certain terminal or function

Advanced Train Control System (ATCS)
Advanced Train Control System is a combination of wayside signal reporting, on board work reporting and message delievery along the railroad. Most commonly it is found along signaled/CTC rail lines and aids in the approximate location of trains, switch positions, route requests and other railroad specific data. A good source on monitoring ATCS data can be found on the ATCS Monitor website. ATCS data is not available on all railroads or lines

Positive Train Control (PTC)
Positive Train Control or PTC is a new GPS and data system to enforce various railroad and federal rules pertaining to train movement. Most railroads will be required to use a form of PTC currently offered by two vendors. This system is designed to be interoperable with other railroads to allow standardizing of data and equipment. Some isolated or passenger railroads may use their own form of PTC such as Amtrak's ACSES on the Northeast Corridor. PTC is independent of other forms of signaling such as ATC/CCS/ATC, but may be overlaid with signal systems. Although there is no dedicated service for PTC by the FCC, railroads have selected the 220MHz spectrum for PTC operations

Train Telemetry
Frequencies listed here are used for train status within the train. EOTD's (end of train device), also known as Fred's (Flashing rear end device) are fixed at the rear of most freight trains. This device is linked to the HOTD (head of train device) also known as a Mary (as opposed to "Fred"). The devices report that the train is moving, air pressure and emergency status of the air valve along with its specific radio ID. This data burst is commonly used by the railfan community that a train is in the listener vicinity. Trains using DP or distributive Power (remotely controlled locomotives) also use 450MHz frequencies to control such locomotives and transmit information such as power or brake setting, unit ID and other status information

UHF Frequencies

Some of these frequencies may be found in repeater service in terminal areas, but the most common use is for half-duplex or simplex linking, telemetry and remote control.
