The idea departure time would be somewhere between 9 and 10 PM. So let's say three trains depart in 30 min intervals (9:00, 9:30, 10:00)the last one will leave at 10 at the latest.

We all know that the 350km/h lines are the ones that require the most maintenance, so in this schedule by the time maintenance starts at midnight the trains will have already past that section (Shanghai-Nanjing). As for the rest of the way, since the first and last train are only one hour apart, at a given section along the way their maintenance group only need to schedule a one hour window for all three trains to pass.
The problem is that you are not only dealing with overnight sleeper trains that depart Shanghai in time to reach Chengdu in morning to be productive. You also have the overnight trains that depart Shanghai in time to reach Chongqing in the morning to be productive... and these pass through the high speed line at a different time of night.

What kind of trains are used for D service? Are they exclusively CRH1, CRH2 and CRH5's? Can a Non-CRH train be classified as D service?

No need for trains that's specially tailored for Chongqing's arrival time. Use the same train just with one stop at Chongqing, sure the arrival time at Chongqing is much earlier but only by a couple of hours, that's better than late.

It's same everywhere. Wires are not made single for a whole line. They are made in sections. That is the place where one section ends and another begins.

Ticket Sales question;
When do tickets for first day runs on new lines, go on sale?
The standard 21 days prior to the date of operation or another time frame?
I am looking to get on a first day train.

Yes, however other HSR in other nations operates daily at 350+kms/hour with identical or similar tech.

I think that it is more likely that the energy consumption and financial costs are due to a lack of maintenance experience and fine-tuning the sets and tracks and infrastructure.

Thus this announcement makes sense. They have learned how to maintain the trains and now will increase speeds, bring maintenance up to that level, raise again, and so on.

Chinese did this in the 80's and 90's, "Speed up campaigns" with old trainsets. Doing this with CRH would be in keeping with recent habit.

I can see them speeding up some lines to top speed +10% once they get this mastered - though there are obvious upper limits.

Wrong. No other country operates HSR at 350 km/h or any speed over 320 km/h, nor has ever.
First country to exceed 300 km/h was France with 320 km/h on LGV Est in 2007. Japan followed suit with 320 km/h on Tohoku Shinkansen since 2013. Spain on AVE reaches 310 km/h. No other country exceeds 300 km/h.

that is my understanding also. however the chinese network was designed and planned to run at higher speeds than the european system and it did so pre 7/23....
