Railroads


 The VHF narrowband frequencies listed below comprise a common pool of narrow-band frequencies for railroad use. It is possible that trunked operation may be found in some areas (mainly terminal areas). Migration to digital is also starting, using the NXDN/Nexedge format.

161.610 (shared with the Marine band) has historically been used as a railroad channel by some roads, but railroad use of this frequency was never particularly prevalent and use for this purpose is likely to be discontinued eventually. It has never been part of the standard AAR frequency plan and was never assigned an AAR channel number.

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.

Automatic Train Control System (ATCS)

ATCS is a control system that uses data to control train movements throughout the United States. ATCS is NOT available in all areas.
For more information check out: ATCS Monitor for Windows

Original frequency assignments were as follows:

  • F-1 - Union Pacific (UP)
  • F-2 - CSX Transportation (CSX)
  • F-3 - Shared ATCS Network
  • F-4 - Burlington Northern Santa Fe (BNSF)
  • F-5 - Norfolk Southern (NS)
  • F-6 - Southern Pacific (SP), also used by CN in the Chicago area 

While these assignments are mostly still valid, any frequency can be used anywhere in the United States, so if you know a line is using ATCS but you can't find anything on the "assigned" frequency, be sure to check the others as well.
