Help please :)

Why i cannot find train from Yichang East to Chongqing in the 11 October or later, it said currently unavailable; but i can find it on the 9 October? I hope this does not mean the station is close?

I am travelling from Zhangjiajie to Yichang East (already Booked) and Yichang east to Chongqing, If the station is close, do I have any possible ways to get to Chongqing from Zhangjiajie. Is there any other route or what should I do, I really need to get to Chongqing because I booked my flight there.

Furthermore, can I have a full refund or cancel of my ticket from Zhangjiajie to Yichang east if the station is close, and how so.

I need help! Urgent.....

Thank you in advance, and bless you who can help.
