Is there any word on what future plans the MOR has for the 'conventional' rail?

Any plans in the works to increase stations, trains, cars pulled, etc. for the N, K, L, T and Z trains?

Those who cannot afford CRH with its 4 classes of fares will want to be able to take hard seats for many decades to come.

When does everything go back to "normal" after Chinese New Year usually? When everybody has returned back to their working cities?

That is correct. Such loops are quite common on older railways in the Alps. The unusual thing here is that the loop is fully in the open air. More commonly it is partly or even fully in the tunnel.

The situation for this line is also unusual because the end point has a vastly higher elevation than the starting point. In other countries mountains are usually just an obstacle with both starting and ending points at modest altitude (<1500 m) thus it is possible to avoid such spirals in newly built railways by constructing "base" tunnels (see Gotthard base tunnel, for example).

A 32.645-km long tunnel is under construction and will eventually replace these loops.

People are returning to work from Feb 16th to 23rd (lunar 15th of first new year month). After Feb 23rd everything will be back to normal.

Again, the part about the grade needed for the slope is clearly understood, except in the pic there does not seem to be such a difference in altitude. Maybe it's an optical illusion, but looking at the initial spot of the loop, and then at the final one, to me there's a difference of just a few meters in height, one that could be easily compensated starting from the point where the train is seen, or a bit earlier. Could there be a different reason for the loop? That's what I was wondering. The part about the "oxygen content" is less clear to me, is the line not electrified?

@Peloso
You can find a similar construction in Brusio, southern ramp of Bernina, only 100 years older.
Please see the altitude difference at the crossing bridge: more than 20 m higher on the bridge than under. This aerial view gives illusion of a quasi-flat land, but it is not!

So every year after the 15th day of the new year everything goes back to normal. All streetvendors are back to normal?

But they say the travel rush will last until 6 of March?

I am quite confident that if MOR had seen the need for the rails to go straight up the slope rather than requiring a rail spiral to be built, they would have done so, what efficiency, best value, provisioning and all that hooha. Although I would have preferred myself if there was no spiral at all... But hey! Who knows

From MOR or MOT's perspective the new year holiday lasts for 40 days. But from business perspective lunar Jan 15th (正月十五) is the last day of the holiday (if not earlier).

Well because it is a true suburban commuter rail, from last year all future C number trains are suburban commuter trains, but they are called Intericty (Chengji, 城际) as they link satellite towns or cities very close to each other. The CRH2 on Jingshan Railway is just a place holder until CRH6 is operational, which itself is derived from the CRH2. It was initially designated Metro Line 22 because future Chinese commuter rail will be operated by local metro companies not MOR, similarly alll the commuter rails around Nanjing also used to carry Metro line numbers.

Passengers rest in the waiting hall of the railway station in Chengdu, capital of southwest China's Sichuan Province, Feb. 18, 2013. A travel peak emerged in Chengdu on Monday after the Spring Festival holiday. (Xinhua/Xue Yubin)

In my area, a commuter rail line with just 120 km/h top speed, and EMU trainsets of limited acceleration (we are finally getting better ones), has 57 km length. And express trains make 6 intermediate stops - in 46...48 minutes.
Non-express trains take 56...58 minutes, and make 5 more stops, total 11.

So, the Jinshan railway is a slow commuter railway.
Jinshan was never called HSR or PDL, it's always designed as a conventional commuter railway, hence the C designation. It's a perfect line for a CRH6.

Has the acceleration of CRH6 been published?

A very interesting news short on the online ticketing system for China Rail, and an industry built to game (err..argument) the system.
