![]() ![]() The possibility of PTC decoding is there if someone decides to, but from what I understand turn-key encryption is part of the PTC system. We may luck out and simply see channels changed to the new frequency sets. So what does this mean? The current ATCS channels will cease to be used eventually, we will lose some sort of coverage, or possibly all radio codeline if the railroads transition to ITCM. Mentions of NS switching to ITCM have been brought up but nothing has been done yet. It is yet to be seen what NS, CN, and CP plan to do. Railroads like BNSF and UP appear to be converting their networks (which both are a mix of technologies: ATCS, ARES, Genisys, etc) and converting to ITCM, a method that uses new and existing PTC infrastructure for CTC control, unifying their systems.ĬSX already is on a similar system, which transmits via IP (basically the same as you connecting to your work network from home) as opposed to radio. So what does this mean? Existing ATCS users have two options: Start moving to the new radio channels, or look at alternative methods. Those frequencies have been added to the ribbon license already, equaling 10 channels each. The AAR holds the nationwide radio license for railroad use. ![]() Unfortunately, the current ATCS channels live in this part of the spectrum.Īs part of the reband, the FCC is alloting two 125kHz portions (896.000-896.125 and 935.000-935.125) to the AAR for future use, provided they transition & remove the current ATCS channels 1-6 by September of 2025. 3MHz of spectrum is to be used for wideband broadband. The FCC is reallocating 900MHz spectrum (896-901MHz and 935-940MHz) for broadband deployment. I’m sure everyone is paying attention to the **** storm of topics in the main group, so let’s clarify things here, where moderation is actually done. ![]()
