The "platform" trains still stop and start, don't they?
...So just how does that NOT negate the "saves energy" argument? PLUS the expense of maintaining THAT network of stop-start trains in good repair...
The only thing this scheme "saves" is the (implied) cost of the new stations, and the schedule time saved by not stopping the fast trains. And they could save the station building costs simply by not building new stations, and using the existing ones instead... which they'd be doing ANYWAY...
Yet another mirage shot down in mid-leap, by shifting from fantasy "thought" to real thought.
(Good thing we carry the expense of paying all these "experts" to come up with these fantasy "savings...")
