Hello Mr. Mazhar, as I know, there is only one train T70 2003/1350 available, it will take about 42 hours, a quite long journey. The cost for the tickets is as the following:
For the soft sleeper, in which four people will share one compartment, the lower berth is CNY1006.00 net, while the upper is CNY964.00 net;
While for the hard sleeper, which means six people will share one compartment, the lower berth is CNY652.00 net, middle one is CNY631.00 net and the upper one is CNY609.00 net.
To save your time, you are suggested to take the flight instead. Hope it helps!
