Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Ok, so I'm agreeing with you!  :-)

Although on the rights of way thing, here in the west the tracks were put in across virgin territory without hindrance from local property owners. Many were formally abandoned. But the desired traffic patterns have changed in the past 50 years and now some new routes are required. Particularly here in the front range of Colorado there is a need to relocate the freight traffic out of the population corridor, but the farmers out east don't like that idea one bit. Originally our trains provided transportation from Denver up to the Union Pacific in Cheyenne, supported the agricultural region north of Denver, and carried silver out of the mountains. What we need now is to move coal (well, depending on what you think about coal) from Wyoming to Texas, to move people from Colorado Springs to Fort Collins, and to move people around within the front range metropolitan areas.

So under your scheme we would have an eastwardly relocated freight system, a new dedicated high speed corridor parallel to the mountains, and a low speed system to support local passenger traffic.

How a railroad proposes to accomplish the increase in capacity is up to the railroad ... but its important to recognize that what the Rapid Rail needs in terms of effective operation is not dedicated right of way, but dedicated use of track with appropriate capacity.

The segregation of rights of way is an artifact of Federal Railroad Administration regulation, so the alternatives facing a local area under the current regulatory structure are narrower than the alternatives facing a national program with the FRA tasked with implementing a new regulatory regime for the Rapid Rail network.

Set the arbitrary part of the current regulatory system to one side. If there is an electrified Front Range rail corridor that can support 100mph freight with reliable delivery ... which is a vital thing to have for Energy Independence, we cannot have the largest urban center in the Mountain West reliant on diesel motor freight ... then sharing that with passenger rail means that the biggest remaining tasks for the passenger rail system are sorting out the rail line into the urban core and the passenger stations along the way.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.

Regional freight (deliveries to grocery stores) could be done with a shared infrastructure. That's a significantly different sort of freight train from what we have now. Whether they could be made to go 100 mph in the front range corridor is another question--there are lots of steep hills.

Here's a picture of the two rights of way (one Union Pacific, ex-D&RGW; one BNSF, ex-Santa Fe) near Castle Rock. Full coal cars go south, empties go north.

The Rapid Freight Rail could be anything in containers that currently goes long distance by truck.

Even where the speed cannot be 100mph in a section, Rapid Rail can be substantially faster than bulk freight.

The key thing is what's called "superelevation", which is how the track is banked going around the curve.

The correct banking to maintain even weight distribution between the two rails depends on the speed. So if slow bulk freight is using the track, those tracks have little or no superelevation, because the banking would put most of the weight on one track, and the maintenance costs and risk of derailment go up.

However, take advantage of the fact that there is room in either one of those corridors for two tracks, and one track can be dedicated to heavy rail, and the other to Rapid Rail. And the Rapid Rail can be superelevated to allow the Rapid Rail to negotiate those curves much faster than the coal trains can do.

Indeed, they can negotiate the curves fast enough that it would be uncomfortable to passengers, which is why passenger trains on Rapid Rail track in a conventional rail right of way will often be tilt-trains.
