That said, isn't it precedent that "increased safety" helps other "restrictions" to be removed (whether it be train, rail, cars, etc), making things more efficient or speeding things up? e.g. More reliable switches, signals, safety mechanisms, make it less risky to reach near the legal USRC speed limit, as an example?
Any additional system can bring "increased safety", but that doesn't necessarily mean that you can lift the regulations that may have existed prior to whatever you are installing. SCS on the subway and PTC both do the same thing - they are an overlay that enforces the existing signal and wayside rules and speeds. They have done nothing to improve the throughput of the lines in and of themselves, and in the case of SCS have actually have slowed the subway system down somewhat.
The new signal system in the USRC will allow for improved speeds and more trains-per-hour - but only in concert with all of the other improvements, such as new signals, new double-slip switches with modified geometry, improved track, etc. A lot of those changes have already occurred to the physical plant, but the old signal system can't take advantage of them. And it may be "safer" in the sense that it is a new system that is less likely to break down, but it certainly isn't going to "improve" the safe running of the railroad any more than the old one did.
