Has anyone done this journey? We actually plan to do it in reverse but can't figure out which rail station we will need in Ostrava., Czech. We know we may need to go through Kowaticz Poland. Thanks.
I answered your question under Czech Republic. You can travel from two Ostrava stations. They are on the same train line and express train stops in both of them. Ostrava-Svinov or Ostrava hlavni nadrazi. Kowaticz does not exist. My educated guess is that you meant Katowice.
Sounds like you're on the right track. Ostrava hl.n. is the main station and you can Google map that location, as well as the other.
I have checked that on the website of PKP (Polish Railways) and can write that there are direct trains from the main station in Kraków to Ostrava hl.n. and a few with a change in Katowice.

Have a nice trip!
