Coldplay ahmedabad special

Hi fellow railway enjoyers!

I am from Bombay attending the Coldplay concert in ahmedabad on 25th. I love rail travel, and WR has launched special coldplay trains (09091/2 for 25th show). I do have a shatabdi reservation to ahmedabad on 25th, but my return journey on the Hapa Duronto is still on RAC (26th technically, after midnight)

09092 on IRCTC website has a weird message saying it is only bookable after 8 AM. Is this 8 AM tomorrow or when? It also says to ask NTES. Earlier NTES said train not found when entering the number; and now NTES website is not working at all.

How and when will the tickets go on sale? Any chance they will be tickets through BookMyShow like the Mumbai local?

If anyone has any idea, please let me know!
