What is ARNK, What sort of transportation it is to travel from Chengdu to Shanghai(Hongqiao)

There is no train arriving at Shanghai Hongqiao Station from CD. They all arrive at Shanghai Station or Shanghai South Station. Most of them are K-type(Kuai Che), and there is one Z-type(Zhi Kuai) available.

Wondering if CD- Shanghai rail is available. The one that takes shorter travel time. 15 hours. I read some posting on internet saying that the bullets service for CD has closed. Want to re confirm and plan my trip. Thanks! And the updated schedule and price?

Not closed. There are 3 D types each day now. All of them departs in early monring, arrives Shanghai at late night. USD100 for second class seat, USD120 for first class seat.
