       | going to mainly update some tracks everywhere (and have two
       | systems running in parallel), or all tracks in selected areas
       | (and have passengers change), or something else?

         | Baltic states attempted this (project Rail Baltica). Lots of EU
         | money were spent with no visible result. I guess, several
         | people in Baltic states became super rich, but in terms of rail
         | infrastructure nothing was done.

         | "Unification to standard gauge on May 31 - June 1, 1886 [United
         | States]
         | 
         | In 1886, the southern railroads agreed to coordinate changing
         | gauge on all their tracks. After considerable debate and
         | planning, most of the southern rail network was converted from
         | 5 ft (1,524 mm) gauge to 4 ft 9 in (1,448 mm) gauge, then the
         | standard of the Pennsylvania Railroad, over two days beginning
         | on Monday, May 31, 1886. Over a period of 36 hours, tens of
         | thousands of workers pulled the spikes from the west rail of
         | all the broad gauge lines in the South, moved them 3 in (76 mm)
         | east and spiked them back in place.[6] The new gauge was close
         | enough that standard gauge equipment could run on it without
         | problem. By June 1886, all major railroads in North America, an
         | estimated 11,500 miles (18,500 km), were using approximately
         | the same gauge. To facilitate the change, the inside spikes had
         | been hammered into place at the new gauge in advance of the
         | change. Rolling stock was altered to fit the new gauge at shops
         | and rendezvous points throughout the South. The final
         | conversion to true standard gauge took place gradually as part
         | of routine track maintenance.[6] Now, the only broad-gauge rail
         | tracks in the United States are on some city transit systems."

           | Those are not nice things. Double decker trains take longer
           | to load/unload than regular trains for only a small increase
           | in capacity. Single deck trains can make more stops in the
           | same amount of time thus serving more people, or they can
           | take less time in the stops thus getting people where they
           | want to be faster. Time is important to humans, anyone who
           | says slow down to others has no idea how they live or where
           | their needs are. If you want to slow down and smell roses
           | that is fine: go to a park and do so - meanwhile a lot of
           | people need less time on transit so they get more time at
           | home with their kids (or whatever else they do in life)
           | 
           | Larger loading gauges are a good things for a lot of reasons,
           | but the ability to run double decker trains is not one of
           | them.

           | Why are wider inter-track requiring larger curves? It should
