Part 1:
Lowe, I have to admit that I did not properly understand your query because you are mentioning Shenzhen and Hong Kong without clearly defining the third destination.
My understanding of your query is that you want to travel from Hong Kong to Shenzhen and then back to Hong Kong. If I am correct, then your best option is to apply for a 5 day Shenzhen VOA on arrival at Lo Wu / Luohu border crossing. You should arrive at the border crossing at about 08:00 - 08:30 in order to be among the first when Luohu visa office opens at 09:00. All you need to take with you is your passport. There you will fill out the form and all the formalities will be done there along with 130 CNY fee payment by card payment. When your visa is granted, you can stay in Shenzhen for up to 5 days and then you can travel to Hong Kong by any border crossing and by taking any mean of transport, high speed train included.
If you plan to fly to Shenzhen from, for example, some European country on the nonstop flight from Europe to Shenzhen and after that plan to travel to Hong Kong, you can do that under 144 hour visa free transit. Here you should just have in mind that you will have to buy your train ticket for Hong Kong in advance, even before you depart from Europe as a proof that you will be really in a transit. Also, please, keep in mind to print out your train ticket confirmation and have it at hand to present it in both Europe and Shenzhen.
