How can I travel from Istanbul (which station, and by what means) to Ankara? I am looking for a bit more details than general track, as in what website can I use to book the tickets, and whether all days are open for travel. I tried the official websites, but I do not know which stations I should be targeting, and I could not get results. (seat61 website has outdated information as it looks, as in not up to 2018, thus the information is NOT ACCURATE!).

https://www.metro.istanbul/en does this even work?
