I should have chosen my words with better care. Unlikely is the better word. For all those mid-block pedestrian walkways forming a circle, a developer would have to re-purpose all 4 of those blocks. That or the city would have to impose such a plan on a developer, which I also consider
unlikely.
I guess I laughed mostly at the generous amount of green space around and oftentimes
between the railroad tracks. I especially like the pond in the middle of Grant's Tower. I notice the train stuff first. I'm a transportation geek more than a urban geek...
Also, I think I may be partly responsible for the conversation on the SLC thread that ended with this:

What I'm worried about is the comet cars as they are very old. I'd like to see them get an interior upgrade so they aesthetically match the bombardiers and get an official "quiet" designation, as well as paneling so they shape with the locomotives and the bombardiers to increase efficiency.

It should be noted that current FrontRunner equipment is rated for 90 mph - both locomotives and cars. They feasibly could go faster if upgraded from UTA's purchasing and refurbishing specs, but that would cost money. The track also is class IV track, meaning that in order to increase speeds it would need to be upgraded to a higher class (class V = 90 mph and class VI = 110, the fastest speed allowed where there are grade-crossings with roads). To upgrade track to those tolerance levels, and also to
maintain that track at that tolerance level, costs exponentially more than maintaining the current class IV track, which is maintained to standard fright-road carrier specs and thus very cheap to maintain by rail standards.
Also, with diesel trains which cannot accelerate very quickly, there is no economical gain in going over 79 mph. The brief time the train would spend at speed would be negligible compared to the cost of extra fuel. Yes diesel trains go just that fast in Illinois and in Michigan, but they are not commuter trains.
My point is not that 110 mph won't happen - it is that it won't happen nearly as soon as people's timelines suppose. UTA would not only need to rebuild (and double track) the alignment, but also electrify it, then buy quick-accelerating EMU (electric multiple unit) trainsets, and then construct passing sidings for express trains to safely bypass stations while at speed.
I can see it happening, but not soon.
