Railroad Frequencies: Non AAR

TrainTenna LP Antenna The railroad frequency lists are broken down into the six sections shown below. Clicking on each link will take will take you to a new page.

Please take a moment to check out our line of "TrainTenna" Rail Band Radio Antennas. DPD Productions TrainTenna antennas are designed specifically for the railroad radio band.
Non AAR


Frequencies Outside the AAR Channel Group

There's frequencies that railroads utilize outside of the typical AAR band plan. Here's a list of some of them...

EOTD (End of Train Devices)
- 457.9375 These are the boxes that are attached to the coupler of the last car in the train. They transmit data to the head end.

EOTD (End of Train Devices)
- 452.9375 This frequency is mostly used on trains in Canada, but it's sometimes used on the head end in America, to "talk" to the EOTD.

VHF Marine Channel 16
- 156.800 This can sometimes be the calling frequency for lift bridges.
Marine Channels 13 (156.650) and 14 (156.7) have also been reported as occasionally used in this way, in some areas.

Advanced Train Control Systems (ATCS)
- This is a system that larger railroads are using on upper 800 and 900 MHz frequencies. The frequencies are being registered under the Association of American Railroads, or the Transportation Technology Center, not the individual railroads that use them. These radio systems basically collect information about train movement and other things along the line. This information is sent to computers and is then used to create the real time displays dispatchers have on their screens, showing train movement and so on. The data isn't always sent through the air, but when it is, it's done in a duplex method using two different frequencies. Small high band yagi antennas at various points along the right-of-way are usually used for these transmissions.
Channel - 1 MCP - 896.8875 BCP - 935.8875 Union Pacific
Channel - 2 MCP - 896.9375 BCP - 935.9375 CSX
Channel - 3 MCP - 896.9875 BCP - 935.9875 Shared ATCS Network
Channel - 4 MCP - 897.8875 BCP - 936.8875 BNSF
Channel - 5 MCP - 897.9375 BCP - 936.9375 Norfolk Southern
Channel - 6 MCP - 897.9875 BCP - 936.9875 ???
