The first segment of this video shows HOT data being decoded, followed by the decoding of EOT data on a different frequency. The second part shows the decoding of DPU data. There is a major train yard / train hub approximately three miles from the position of my radio.

452.9375 is the frequency I used to listen to the head-of-train (HOT) transponder.
457.9375 is the frequency I used to listen to the end-of-train (EOT) transponder.
457.9250 is the frequency I used to listen to the Distributed Power Unit (DPU) signal.

Signals were decoded using SoftEOT and SoftDPU programs. The software can be downloaded from here after requesting membership to the group:
