Wow, just something like 1200 baud FSK on 70cm. That’s stupid simple, and stupid. They could use cellular modems (the locomotives already have one, normally) or LoRaWAN or…anything without even trying and it would be an improvement.
If you have rail standards of the 21st century cellular is absolutely what you should be using for rail see: GSM-R . Apparently the DOT is even looking at this.
Now you’d need to build cellular infrastructure along your lines for that system. US rail owners are terminally uninterested in building or maintaining rail infrastructure so that’s not particularly likely to happen unless mandated.

The answer to a hyper-localized security issue isn’t attaching the equipment to an insecure network nor is it shifting to use insecure IoT type devices.

But $!
For that one guy.
Outweighs the safety of a nation.
Don’t you get it yet? You don’t live in a society, you live in capitalism.
